PVP改性吸附剂处理印染及重金属废水研究进展

Research progress of PVP modified adsorbent in the treatment of dyeing and heavy metal wastewater

综述了聚乙烯吡咯烷酮(PVP)改性吸附剂国内外的研究进展,包括改性碳基吸附剂,黏土基吸附剂,金属类吸附剂及其他类吸附剂。阐述了PVP改性吸附剂在印染废水及含重金属离子废水处理方面的应用,并对PVP改性吸附剂未来发展方向进行了展望,以期为后续学者进行PVP改性吸附剂研究提供理论支持。

The research progress of polyvinylpyrrolidone(PVP)modified adsorbents at home and abroad was reviewed,including modified carbon based adsorbents,clay based adsorbents,metal adsorbents and other adsorbents.The application of PVP modified adsorbent in the treatment of dyeing wastewater and wastewater containing heavy metal ions was described,and the future development direction of PVP modified adsorbent was prospected,in order to provide theoretical support for subsequent scholars to study PVP modified adsorbent.
