摘　　要：阳离子表面活性剂改性沸石作为一种高效除氮的吸附剂已经被广泛地关注。但CPB和HDTMA改性沸石在吸附性能和除氮机制上的差异却未见报道。通过制备CPB和HDTMA改性天然斜发沸石颗粒用于污水除氮,比较二者的吸附能力及吸附机制。Cationic surfactant-modified zeolites as a highly effective nitrogen removal adsorbent have been widely concerned.However,the differences between the adsorption properties and nitrogen removal mechanism of CPB and HDTMA modified zeolites have not been reported.The natural clinoptilolite particles modified by CPB and HDTMA were used for nitrogen removal of wastewater,and their adsorption capacity and adsorption mechanism were compared.

关 键 词：CPB HDTMA 改性沸石 除氮 吸附
