酸性品红/Cr(Ⅵ)复合污染的吸附富集-原位光催化综合处理
Comprehensive treatment of acid fuchsin/Cr(Ⅵ)composite pollution by adsorption enrichment and in-situ photocatalysis
摘要
Abstract
Heavy metals and organic compounds are common pollutants in water bodies,it is of great importance to treat them and reduce the resulting complex pollution.Gel/CS/PPy/Zn3In2S6 composite material was prepared by incorporating Zn3In2S6 into a conductive gel Gel/CS/PPy composed of PPy(polypyrrole),Gel(gelatin)and CS(chitosan).The structure and performance of the materials were tested and analyzed using SEM,FT-IR,UV-vis-NIR,etc.Removal effect of Gel/CS/PPy/Zn3In2S6 on heavy metal and organic compound pollution was studied with AF(acid fuchsin)and Cr(Ⅵ)ions as test pollutants.The results show that Gel/CS/PPy/Zn3 In2 S6 can simultaneously adsorb AF and Cr(Ⅵ)with adsorption efficiency of 93.98％and 95.14％.Under the condition of light,Zn3In2S6 can degrade AF and reduce Cr(Ⅵ)in gel simultaneously.After 10 adsorption enrichment and in-situ photocatalytic cycles,the adsorption efficiencies of AF and Cr(Ⅵ)can still reach 60.44％and 73.15％.The combined approach of adsorption enrichment and in-situ photocatalytic degradation offers a novel strategy for addressing complex water pollutants,demonstrating significant potential for practical applications.关键词
