In this study, CuCo layered double hydroxide/biochar composite (CuCo LDH/BC) was prepared and employed for activating HO to degrade ciprofloxacin (CIP), a common fluroquinolone antibiotic detected in water environment. The as-synthesized catalysts were also comprehensively characterized to study the physiochemical properties. For the catalytic activity, the degradation rate of CuCo LDH/BC to CIP was approximately 1.5 times higher than that of CuCo LDH. The improved catalytic activity can be ascribed to the synergistic effect between CuCo LDH and BC, such as more functional groups, accelerated electron transfer, and varied charge distribution. Meanwhile, CuCo LDH/BC/HO could degrade CIP efficiently in a wider pH range comparing with CuCo LDH/HO, and the efficiency was approximately 84.7% at neutral pH within 90 min. The generation of OH, O and O in CuCo LDH/BC/HO system were then verified by electron spin resonance (ESR) technology. The quenching experiments indicated that both non-radical pathway (O) and radical pathway (OH, O) led to CIP degradation, in which O and O made major contribution. Then, the intermediate products of CIP during catalytic reaction were monitored by high-performance liquid chromatography-mass spectrometry (HPLC-MS), and the environmental risk of these degradation intermediates was tested through seed germination experiments. This study tends to provide valuable information for LDH/BC application in heterogeneous Fenton-like reaction.

Ltd.

[Objectives] An analytical method was established for determining fosthiazate residue in ginger by gas chromatography with flame photometric detector(GC-NPD) to evaluate the safety of fosthiazate in ginger. [Methods] The fosthiazate residue in ginger was extracted with dichloromethane, and subjected to sodium chloride salt-out and liquid-liquid extraction with hexane and dichloromethane(the plant and soil samples had no need for the later two steps). The analysis was performed on gas chromatograph equipped with a flame photometric detector(GC-FPD), and the fosthiazate residue was quantitatively determined by calculating the peak area. [Results] The results of degradation dynamics showed that the half-life of fosthiazate was 7.2-8.7 d in ginger plants, and was 9.9-19.8 d in the soil. The results of the final residue test showed that after applying the fosthiazate granules according to the recommended high dose(active component 58.2 g a.i/m^2,WK) and low dose(38.8 g a.i/m^2,WK) once, the final residual amounts of fosthiazate in the ginger and soil were estimated to be <0.02 mg/kg and <0.02-0.103 mg/kg, respectively, while no fosthiazate residue was detected in all control samples(<0.02 mg/kg). The maximum residue limit(MRL) of fosthiazate in ginger was not established in China, and was 0.2 mg/kg in Japan. [Conclusions] The method was proved to meet the basic requirements of pesticide residue analysis on sensitivity, accuracy and precision and have good linearity. It is recommended that when using fosthiazate granules to control root-knot nematode and root rot in ginger, it is applied at the highest dose of 38.8 g ai/m^2,WK once 30 d before ginger cultivation to treat the soil, and ginger is harvested in the ginger harvest period.

Simultaneous regulation of the coordination environment of single-atom catalysts (SACs) and engineering architectures with efficient exposed active sites are efficient strategies for boosting peroxymonosulfate (PMS) activation. We isolated cobalt atoms with dual nitrogen and oxygen coordination (Co-N O ) on oxygen-doped tubular carbon nitride (TCN) by pyrolyzing a hydrogen-bonded cyanuric acid melamine-cobalt acetate precursor. The theoretically constructed Co-N O moiety on TCN exhibited an impressive mass activity of 7.61×10 min mol with high O selectivity. Theoretical calculations revealed that the cobalt single atoms occupied a dual nitrogen and oxygen coordination environment, and that PMS adsorption was promoted and energy barriers reduced for the key *O intermediate that produced O . The catalysts were attached to a widely used poly(vinylidene fluoride) microfiltration membrane to deliver an antibiotic wastewater treatment system with 97.5 % ciprofloxacin rejection over 10 hours, thereby revealing the suitability of the membrane for industrial applications.

Polluted stormwater (PSW) treatment is becoming increasingly important because of the existence of multiple pollutants from non-point pollution sources. Alfalfa biochar loaded with Mg/Fe layered double hydroxide (AF-LDH) was successfully synthesized to remove trace metal(loid)s from stormwater. The adsorption kinetics and isotherms of metal(loid)s in a mono-component system and the reusability of the composite materials was investigated in this study. The result showed that the maximum removal efficiency for Pb(II), Cu(II), Zn(II), Cd(II), As(V), and Cr(VI) were 98.98 %, 98.11 %, 97.88 %, 97.71 %, 98.81 %, and 50.89 %, respectively, when added calcined AF-LDH (AF-LDO) composite material to the multi-component solution. The AF-LDH and AF-LDO could efficiently remove trace pollutants (10-100 μg/L) from multi-component solution, especially for AF-LDO, which could completely remove the tested six trace metal(loid)s. Furthermore, Fourier transform infrared spectra and X-ray diffraction characterizations supported the Mg/Fe layered double hydroxide reconstruction. The main mechanisms of Pb(II), Cu(II), Zn(II), and Cd(II) (cationic metals) removal were ion exchange and surface precipitation, whereas As(V) and Cr(VI) (anionic metals) were mainly dislodged through the formation of surface complexation, electrostatic attraction, and interlayer anion exchange, concerning the -OH and -COOH of AF-LDH. Importantly, the results of the column experiment demonstrated that AF-LDO was superior to AF-LDH for anionic metal removal from stormwater. In this study, we synthesized AF-LDH and AF-LDO for trace metal(loid) removal and proposed a new and practical approach for stormwater purification.

Biochar has been considered as a promising environmental-friendly catalyst to activate peroxydisulfate (PDS) for contaminant degradation. In this study, a series of autogenous N-rich biochar derived from Spirulina were prepared by K 2 CO 3 impregnation (NPSBs). The pyrolysis temperature and the rational design of morphology by K 2 CO 3 had a significant influence on the performance of NPSBs to activate PDS. The NPSB-700 was capable of degrading 97.59% sulfamethoxazole (SMX) within 40 min because of the high surface area, high defect degree, and good electrical conductivity . The accelerated electron transfer and the generation of 1 O 2 were elucidated to be the dominant pathways for SMX degradation. It has been proven that this is a process of reducing toxicity. Furthermore, NPSB-700 also showed excellent degradation performance to various pollutants. This study provides a facile modification strategy of Spirulina -based catalysts and deepens the comprehension of persulfate activation via nonradical oxidation .

Globally, roughly 380 trillion liters of wastewater are generated annually, with a significant portion remaining untreated due to expensive treatment and lack of expertise, consequently, leading severe environmental and public health problems. This research aims to identify the most environmentally sustainable and eco-friendly approach to wastewater treatment. Results shows that, agricultural lignocellulose-based biomass (ALCB) biochar is highly effective for wastewater treatment due to its abundance, cost-effectiveness, and excellent adsorption properties. The ability of sustaining high carbon content makes it a valuable carbon sink beneficial for the carbon reduction. Annually, ALCB is widely available as a byproduct in developing countries like China 716 (million tons) Mt, India 605 Mt, Brazil 451 Mt, Pakistan 285 Mt as well as in developed regions U.S.A 682 Mt, and Europe 580 Mt. Pyrolysis, gasification, and torrefaction are mostly used methods for ALCB biochar production. Physicochemical properties including surface area, porosity, functional groups, pH, and elemental composition notably affected by production methods, feedstock types and reactor designs determine the adsorption performance and environmental safety of ALCB biochar. The adsorption mechanisms of the organic and inorganic pollutant on biochar are ion exchange, complexation, electrostatic attraction, pore-filings, and physical adsorption, etc. LCA assessment revealed that the utilization of ALCB biochar on wastewater treatment offers several economic, environmental, and educational benefits through the aspect of waste management, revenue generation, job creations, pollution control, trading and skill developments.

4-nitrophenol (4-NP) in industrial wastewater is harmful to both ecological environment and human health even in the very low concentration in the environment. Catalytic hydrogenation, which converts toxic pollutants from wastewater into high-value industrial feedstocks, is a coveted treatment option, but the design of suitable catalysts has been a challenge in the field. In this work, the functionalized conjugated microporous polymers (CMPs) anchored Ag nanocatalysts could effectively catalyze the hydrogenation of 4-NP in wastewater to 4-aminophenol (4-AP) with the rate constant k of 0.01544 s −1 . We further optimized the morphology of the CMP substrate to stabilize Ag nanocatalysts and integrated the composite into a modular unit for continuous flow wastewater treatment with an outstanding permeation flux of 1603 L m −2 h −1 (LMH). These findings provide an effective strategy to design noble metal catalysts for catalytic hydrogenation and could potentially be modularized for use in mountainous and isolated communities.

Air quality network data in China and South Korea show very high year-round mass concentrations of coarse particulate matter (PM) between 2.5 μm and 10 μm aerodynamic diameter, as inferred by the difference between PM10 and PM2.5 observations. This coarse PM averages 47 μg m-3 in the North China Plain (NCP) region in 2015-2019 and 21 μg m-3 in the Seoul Metropolitan Area (SMA). It is dominantly contributed by urban fugitive dust, rather than by natural dust as is often presumed. Concentrations decreased by 21% from 2015 to 2019 and further dropped abruptly in 2020 due to COVID-19 reductions in construction and vehicle traffic. This anthropogenic coarse PM is generally not included in air quality models but acts as a sink of nitric acid (HNO3), thus affecting fine particulate nitrate which is a major air quality concern in China and South Korea. GEOS-Chem model simulation of surface and aircraft observations from the KORUS-AQ campaign over the SMA in May-June 2016 shows that consideration of anthropogenic coarse PM largely resolves the previous model overestimate of PM1 nitrate. Anthropogenic coarse PM in the model increases the sensitivity of PM2.5 nitrate to ammonia (NH3) emission in winter. In summer, anthropogenic coarse PM directly affects PM2.5 nitrate by HNO3 uptake, and we find that the decrease of anthropogenic coarse PM over 2015-2019 offset the PM2.5 nitrate reductions expected from decreasing NOx and NH3 emissions.

energy demand for space cooling and heating in buildings is a primary contributor to the total building energy consumption. Its rapid increase calls for an urgent need to utilize renewable energy sources and associated energy-efficient technology in the building sector. Among different renewables, geothermal energy has been widely adopted due to its easy access and low impact on the environment. In this study, a new earth-to-air heat exchanger (EAHE) system with vertically buried tubes was proposed. Compared to the conventional EAHE systems, its advantages mainly include high geothermal energy utilization efficiency and ease of condensate water discharge. To evaluate the thermal performance and cooling capacity of this system, an experimental set-up was established and a series of tests were conducted in hunan, China. The results show that the outlet air temperature of this system ranged from 22.4℃ to 24.2℃ as the air flow velocity set at 1.0 m/s, enabling it to be used as an energy efficient technology for summer cooling of buildings. Meanwhile, both inlet air temperature and air flow velocities have an important influence on the system’s cooling capacity.
