摘要
Abstract
Emulsion liquid membrane technology has high efficiency,good selectivity,simultaneous extraction and stripping characteristics,is not affected by the pollutant concentration limits,has been widely used in organic compounds,extraction and recovery of heavy metal ions,biomedical separation and other fields.This paper focuses on the research progress of emulsion liquid membrane extraction of chromium(VI)at home and abroad. The extraction mechanism of chromium(VI)by emulsion liquid membrane is presented. The effects of different process parameters on extraction were summarized,and the synergistic effect of various influencing factors on extraction efficiency was also introduced. Combined with the existing problems in the process of extraction,the research direction of emulsion liquid membrane in the future is prospected. How to improve the stability of emulsion liquid membrane is still the focus of research in the future.关键词
