The effect of Hydroxypropyl-β-cyclodextrin(HP-β-CD) on the removal of Aroclor1242-one kind of PCBs(Polychlorinated biphenyls)-contaminants from soil has been investigated. The interaction of HP-β-CD with PCBs in solution yielded the formation of a water-soluble inclusion complex, which gave an increase in PCBs solubility, PCBs can be removed effectively from soil by HP-β-CD elution. The efficiency of washing can be increased by increasing the concentration of HP-β-CD and the number of washing respectively. The washing efficiency of Aroclor1242 from soil is almost 0 by distilled water while 81% by 50g/L of HP-β-CD solution after five times washing. The results obtained indicate the high extract power of HP-β-CD toward PCBs polluted soil and potential use of HP-β-CD for in situ remediation of PCBs or other low-polarity organic contaminated soils. © 2008 IEEE.

A new di-function adsorbent (JN-3) was prepared by sulfhydryl modified. Comparing with Amberlite XAD-4 and NDA-150, the equilibrium adsorption for phenol on the JN-3 from aqueous solutions was tested, perfect adsorption capacity was shown. Pb2+ can be also removed by JN-3 because of the chelate interaction between sulfhydryl groups and metal ions. This adsorbent could be used in removal of combine pollutants such as phenolic compounds and heavy metal ions from waste streams.

The efficacy and environmental effects of using metal–organic frameworks (MOFs) for the remediation of arsenic (As)-contaminated soil, a significant global problem, remain unclear. This study evaluated MIL-88A(Fe) and MIL-101(Fe) coupled with ramie ( Boehmeria nivea L.) for As-contaminated soil remediation. A soil incubation experiment revealed that 10,000 mg kg −1 MIL-88A(Fe) and MIL-101(Fe) reduced As bioavailability by 77.1 % and 65.0 %, respectively, and increased residual As fractions by 8 % and 7 % through Fe-As co-precipitation and adsorption. Divergent environmental effects emerged, which were probably due to differences in the framework structures and organic ligands: MIL-88A(Fe) improved soil urease activity and bacterial diversity, whereas MIL-101(Fe) induced acidification (decreasing soil pH by 25 %) and salinity stress (elevating soil electrical conductivity (EC) by 946 %). A pot experiment showed that 1000 mg kg −1 MOFs enhanced ramie biomass via As immobilization, whereas 5000 mg kg −1 MIL-101(Fe) suppressed growth because exposure to the MOF caused root damage. The MOFs enriched Pseudomonas (As-oxidizing) and suppressed Dokdonella (pathogenic), enhancing plant resilience. Notably, 100 mg kg −1 MIL-101(Fe) increased As translocation to stems (14.8 %) and leaves (27.6 %). Hydroponic analyses showed that 50–200 mg L -1 MIL-101(Fe) mitigated As-induced chlorophyll degradation (elevating Soil and plant analyzer development (SPAD) by 12.8 %–28.3 %), whereas 500 and 1000 mg L -1 induced oxidative stress (reducing SPAD by 4.2 %–10.7 %). This study provides valuable insights into using Fe-based MOFs in soil remediation and highlights their beneficial and harmful effects.

The assessment system for water ecological civilization city is suggested, including a rule layer with 5 factors and an index layer with 19 defined indexes based on the connotation of water ecological civilization. Assessment model is developed based on the variable fuzzy set, which reasonably identifies the relative membership degree and function of simple index and standard interval of each level. Taking Zhuzhou city, China, as an example of comprehensive evaluation of water ecological civilization, the results show that the proposed model can rationally determine ecological civilization grade considering all related indicators. The eco-civilization of water in Zhuzhou city is in a low level: non-harmonious. The results of this paper could provide scientific references for city water management and environment protection. © 2016 by World Scientific Publishing Co. Pte. Ltd.

Saline water desalination serves as an important route to increase freshwater supply, while capacitive deionization (CDI) has emerged as a promising technique to tackle this issue. To boost the successful application of CDI, development of advanced electrode materials is vital. Herein, we innovatively designed and synthesized a sophisticated Prussian blue/dimorphic polypyrrole composite for the hybrid CDI (HCDI). Specifically, the nanoparticle-like polypyrrole (PPy) in situ distributed on the surface of stepped hollow FeHCFe nanocubes, while the coexisting nanotube-like PPy interconnected the discrete stepped hollow FeHCFe nanocubes. The introduction of PPy nanoparticles/nanotubes promoted both electron and ion dynamics, and improved the electrochemical activity of FeHCFe. Meanwhile, the FeHCFe nanocubes with concave stepwise architecture on each side offered large accessible contact area for electrolyte, reduced Na + migration path, improved tolerance for lattice expansion, and optimized redox sites for Na + storage. Through such unique structural design and synergistic combination, the FeHCFe/PPy with appropriate component ratio achieved a remarkable desalination capacity and a fast desalination rate along with excellent cycling performance, outperforming other related materials. Moreover, the treated solution can meet the drinking water standard within 6 min via the use of six tandem HCDI cells. Density functional theory (DFT) revealed the mechanism of Na + capture process and provided a fundamental understanding of the rapid Na + migration and large Na + storage capability. This study provides insights into ration design of superior electrode materials for high-performance electrochemical water desalination.
