Summary: Access to safe drinking water is a significant concern in China, particularly in rural areas. While the government has made efforts to increase access to tap water, the rate is still considerably lower than in urban areas and unevenly distributed across the country. Additionally, electricity, mainly electric kettles, contributes to the boiling of water, with 69% of households using this method. Further intervention and investment are necessary to improve drinking water safety in poor and remote rural areas.

Summary: In this paper, a novel needle-shaped Zinc organic framework (Zn-MOF/CE) was formed on the surface of a functionalized graphite electrode, providing a systematic alternative electrode. The ZnMOF modifier was characterized by XRD, FT-IR, FESEM-EDS mapping, and N2 sorption. The modified electrode exhibited high stability and conductivity, making it an ideal working electrode. The redox process of hydroquinone at the modified electrode surface was optimized and modeled using the central composite design method, showing the best performance at a scan rate of 560 mV/s and pH of 9.9. Frequency domain using bode plots and CCD results could be employed for stability and electrode material performance prediction.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.
