分离液体的膜

本文概述了7种以高分子为膜材料、用于混合液体分离的膜分离过程,即离子交换膜与电渗析、反渗透、超滤、微孔过滤、膜萃取、渗透汽化和膜蒸馏。对其原理、高分子膜材料、应用和发展趋向作了简要介绍;并阐述了我国膜分离发展的现状和展望。

The Membranes for Separation Liquid

This paper outlines seven membrane separation processes for liquid separation with polymer material membranes, i. e. ion exchange membrane and electrodialysis, reverse osmosis (hyperfiltration), ultrafiltration, microfiltration, membrane extraction, pervaporation and membrane distilation. The principle, polymer membrane materials used, application and derelopmemt trend of each process have been simply elucidated. And the status as well as the perspective of membrane separation of China have been reviewed.
