Adsorption of Reactive Brilliant Red X-3B from Aqueous Solution by Polypyrrole/Calcium Rectorite Composites: Adsorption Behavior and Mechanism

引用

IOP Conference Series. Earth and Environmental Science 2020年第1期453卷

作者： Guo, Qihua Xu, Yaolei Kun Yong Chen, Ran Wang, Xiaofeng Chen, Jinyi School of Chemistry and Environmental Engineering Wuhan Institute of Technology Wuhan China Hubei Environmental Engineering Technology Research Center for Engineering Pollution Control Wuhan China Key Laboratory of Green Chemical Engineering Process of Ministry of Education Wuhan China

In this study, polypyrrole/calcium rectorite clay composites (PPy/REC composites) were prepared by in-situ polymerization of pyrrole monomer to adsorb reactive brilliant red X-3B from aqueous solution. The results of XRD showed that the clay flakes exfoliated in the prepared composites. The SEM results showed that PPy had good dispersibility on clay sheets. The adsorption mainly depended on the initial pH value of the solution, and the optimal adsorption of reactive brilliant red X-3B was achieved when the pH value was 2.0. The removal rate of PPy/REC composite was much higher than that of PPy homopolymer. The adsorption kinetic data of reactive brilliant red X-3B at three initial concentrations (100, 150 and 200 mg/L) were best fitted by the pseudo-second-order model, indicating that the concentration gradient of the adsorbent was the driving force of the adsorption process. The adsorption isotherm accorded with the Langmuir isotherm model, and the maximum adsorption capacity was 232.56 mg/g at 298 K. The PPy/REC composites could be regenerated and reused for 5 continuous adsorption-desorption cycles without losing the removal efficiency of the original reactive brilliant red X-3B. XPS, zeta potential and FT-IR results showed that the removal mechanism of reactive brilliant red X-3B was related to electrostatic interaction and ion exchange.

引用

Advances in difference equations 2016年第1期2016卷 267页

作者： Xiaozheng Fan Yan Wang Manfeng Hu School of Science Jiangnan University Wuxi 214122 China. School of Internet of Things Jiangnan University Wuxi 214122 China. Key Laboratory of Advanced Process Control for Light Industry Ministry of Education Institute of Automation Jiangnan University Wuxi 214122 China.

In this paper, the fuzzy [Formula: see text] output-feedback control problem is investigated for a class of discrete-time T-S fuzzy systems with channel fadings, sector nonlinearities, randomly occurring interval delays (ROIDs) and randomly occurring nonlinearities (RONs). A series of variables of the randomly occurring phenomena obeying the Bernoulli distribution is used to govern ROIDs and RONs. Meanwhile, the measurement outputs are subject to the sector nonlinearities ( the sensor saturations) and we assume the system output is [Formula: see text], [Formula: see text]. The th-order Rice model is utilized to describe the phenomenon of channel fadings by setting different values of the channel coefficients. The aim of this work is to deal with the problem of designing a full-order dynamic fuzzy [Formula: see text] output-feedback controller such that the fuzzy closed-loop system is exponentially mean-square stable and the [Formula: see text] performance constraint is satisfied, by means of a combination of Lyapunov stability theory and stochastic analysis along with LMI methods. The proposed fuzzy controller parameters are derived by solving a convex optimization problem via the semidefinite programming technique. Finally, a numerical simulation is given to illustrate the feasibility and effectiveness of the proposed design technique.

Molecular stacking modes, generally classified as H-, J-, and X-aggregation play a key role in determining the optoelectronic properties of organic crystals. However, the control of stacking transitions of a specific molecule is an unmet challenge and a priori prediction of performance in different stacking modes is currently not possible. Herein, unexpected stacking transition from H- to J- and X- aggregation is observed in the crystal structure of a minimalistic aromatic molecule, 4,4’-bipyridine, upon co-assembled with N-acetyl-L-alanine, a non-aromatic amino acid derivative. This stacking transition improves the physicochemical properties of the co-crystals, including a large red-shifted emission, enhanced chirality, improved thermal stability and mechanical properties. While the single crystal of 4,4’-Bpy shows good optical waveguiding and piezoelectric properties, the co-crystal has a significantly lower band-gap and improved conductivity. This demonstrates the first example of H- to J- and X- packing transition of a minimalistic model by co-crystal aggregation and provides a proof-of-concept strategy for organic optoelectronics design. © 2020, The Authors.

The sustainable utilization of biochar produced from biomass waste could substantially promote the development of carbon neutrality and a circular economy. Due to their cost-effectiveness, multiple functionalities, tailorable porous structure, and thermal stability, biochar-based catalysts play a vital role in sustainable biorefineries and environmental protection, contributing to a positive, planet-level impact. This review provides an overview of emerging synthesis routes for multifunctional biochar-based catalysts. It discusses recent advances in biorefinery and pollutant degradation in air, soil, and water, providing deeper and more comprehensive information of the catalysts, such as physicochemical properties and surface chemistry. The catalytic performance and deactivation mechanisms under different catalytic systems were critically reviewed, providing new insights into developing efficient and practical biochar-based catalysts for large-scale use in various applications. Machine learning (ML)-based predictions and inverse design have addressed the innovation of biochar-based catalysts with high-performance applications, as ML efficiently predicts the properties and performance of biochar, interprets the underlying mechanisms and complicated relationships, and guides biochar synthesis. Finally, environmental benefit and economic feasibility assessments are proposed for science-based guidelines for industries and policymakers. With concerted effort, upgrading biomass waste into high-performance catalysts for biorefinery and environmental protection could reduce environmental pollution, increase energy safety, and achieve sustainable biomass management, all of which are beneficial for attaining several of the United Nations Sustainable Development Goals (UN SDGs) and Environmental, Social and Governance (ESG). © 2023 The Authors

Efficient treatment of pure terephthalic acid wastewater with Na 2 S 2 O 8 based on thermal activation

Terephthalic acid (TA) is an important industrial raw material. A large amount of wastewater, mainly containing TA, is generated in the pure terephthalic acid (PTA) producing process. In this study, an advanced oxidation process based on persulfate like Na 2 S 8 O 8 was proposed to degrade TA. The result showed that higher temperature was conducive to degrade TA due to better thermal activation effect, causing more radicals to generate, and the removal ratio of TA reached to a high level of 95.2% at 80 °C. Meanwhile, the TA removal efficiency (maximum 97.4%) at alkaline conditions was better than that in both acidic conditions (about 94%) and neutral condition (85%) at 80 °C. It implied the removal of TA could be carried out effectively in thermal activation mode, and further intensified in the alkaline environment on the basis of thermal activation. The generation of free radicals with thermal activation could be used to explain the degradation mechanism of the organic. Overall, a max total organic carbon (TOC) removal of 97.7% could be achieved, and a probable reaction pathway was proposed with the identification of the intermediate products during TA oxidation. These results could provide a theoretical basis for lower energy consumption and effective treatment of PTA industrial wastewater , which is usually at 75–85 °C and suitable for thermal activation.

Photocatalytic hydrogen peroxide (H 2 O 2 ) production has emerged as an attractive alternative to the traditional anthraquinone process. However, its performance is often hindered by low selectivity and sluggish kinetics of oxygen reduction reaction (ORR). Herein, we report an anthrazoline-based supramolecular photocatalyst, SA - SADF - H + , featuring an unsymmetric protonation structure for H 2 O 2 photosynthesis from water and air. The introduction of unsymmetric protonation disrupts the initial mirror symmetry of SADF , significantly enhancing the molecular dipole and facilitating efficient charge separation and electron transfer. Additionally, this modification increases the hydrophilicity of SA - SADF - H + , enabling the interaction of water and dissolved oxygen with the catalytic sites. The altered electron density distribution creates numerous dual active sites for Yeager-type O 2 adsorption, facilitating an efficient ORR towards H 2 O 2 via a direct one-step two-electron pathway. Notably, SA-SADF - H + achieves an outstanding photocatalytic H 2 O 2 production at a rate of 4666.7 μmol L −1 h −1 , with a remarkable solar-to-chemical conversion (SCC) of 1.35 %, surpassing most organic photocatalytic systems. Furthermore, SA - SADF - H + demonstrates remarkable photocatalytic antibacterial activity, achieving 100 % antibacterial efficiency against Staphylococcus aureus within 60 min.
