| 摘 要： | 本文对乳状液膜从含铬（VI）废液中提取铬进行了研究，考察了影响铬迁移的几种因素：内外水相pH、表面活性剂、流动载体、添加剂等．结果表明，在合适的操作条件下，当废水中铬的含量在4．8×10－3mol·L－1时，经过一级液膜处理，废水中铬的提取率可达99％以上，提余液可以直接排放．

| Abstract: | In this article,the separation of chrome from waste water with emuision liquid membranes was studied. The effect of some factors on the transport of chrome was reserched in membrane processes. These factors are pH in water phase, surfactant, mobile carrier, and additive. Under suitable conditions,the experiment shows that the transpott rates of chrome can exceed 99% when the density of chrome is 4. 8 ×10-3mol·L-1. The feed may reach the environmental standard after dealing with one-stage liquid membrane processes. |
