【摘要】 纳膜分离过程是一种选择性高、操作简单和能耗低的分离技术,已在各工业领域和科学研究中得到广泛的应用。纳滤过程的诸多优点,使其在石油化工、医药和食品等领域的非水溶液体系中具有极大的潜在应用价值,而传统的纳滤膜难以拓宽到非水溶液体系中使用,为此进一步研究和发展耐溶剂纳滤膜,对于拓宽纳滤过程的应用极其重要。目前,耐溶剂纳滤膜已成为膜分离科学领域的研究热点,在现有报道的文献基础上,本文综述了有关在非水溶液体系中使用的耐溶剂纳滤膜制备的研究进展,并对未来的发展方向提出了建议。更多还原

【Abstract】 Nanofiltration(NF) is a promising membrane technology for the food,wastewater treatment,refining and pharmaceutical industries due to the advantages of low operating pressure,low investment and low operation and maintenance cost.However,an industrial NF membrane used for aqueous system is often unsuitable for intensive solvent system because of its extensive swelling,which leading to a drastic loss of selectivity.To realize these applications,the NF membranes must be desirably stable in the organic solvents.Many researchers have focused on improving the stability of the NF membranes,especially the solvent resistant nanofiltration(SRNF) membranes.This paper provides an overview of the recent advances of SRNF in the non-aqueous systems,including the preparation of SRNF.The development trend of SRNF and existing problems is discussed.更多还原
