摘　　要：综述了近年来各种改性沸石对于硝酸盐污染物吸附处理的研究进展,从表面活性剂改性、酸溶液改性、碱溶液改性和金属盐溶液改性几个改性方法出发,介绍了这几种方法对天然沸石的改性机理,对改性沸石吸附处理水中硝酸盐污染物的前景进行了展望,包括寻找新型改性材料、将几种不同改性方法进行组合,以减少单一改性方法不足,为后续新型改性沸石方法提供参考。Many kinds of modified zeolite in recent years was reviewed in this paper for the research progress of nitrate adsorption treatment,from surfactant modification,modification acid solution,alkali solution and metal salt solution modified several modification methods,introduces the several methods of natural zeolite modification mechanism,and finally,the modified zeolite adsorption water nitrate pollution was discussed,the prospect of it includes searching for new modified materials and combining several different modification methods,so as to reduce the shortage of a single modification method and provide reference for the subsequent new modified zeolite methods.
