摘要
纳滤是介于反渗透和超滤之间的一种膜分离技术 ,该膜曾被称为“低压反渗透膜”、“超渗透膜”或“疏松反渗透膜” .本文综述了纳滤膜的特性、分离机理、研究现状及其在饮用水、制药业及石油开采与提炼过程中的应用 ,并对其更广泛的发展前景进行展望 .
The membrane separating technology in between reverse osmosis and ultrafiltration, nanofiltration used to be called as 'low pressure reverse osmosis' 'ultra-osmosis' or 'loose reverse osmosis'. The characteristics, separation mechanism, current research situation and the application of nanofiltration membranes in preparation of drinking water, pharmacy industry and exploiting and extracting petroleum are reviewed in this paper. Because of its characteristics, nanofiltration membrane have broad application prospects, and the research on its preparation and application causes researchers′ attention. A brief prospect in this field is given.
