改性有机膨润土对苯酚吸附性能的研究

Study on Adsorption of Phenol by Modified Organobentonite

摘要: 利用无机试剂H2SO4、H2O2,对钠基膨润土进行预处理,再用溴化十六烷基三甲基铵(CTMAB)进行改性,并利用改性有机膨润土对苯酚进行吸附研究。实验结果表明,最佳改性土是利用φ=2%的H2O2预处理、经30 g/L CTMAB改性的有机膨润土。

Abstract: A new organobentonite was developed by pretreatment of sodium bentonite with H_(2)SO_(4) or H_(2)O_(2) and followed by modifying with cetyltrimethyl-ammonium bromide(CTMAB).The adsorption properties of the new product to phenol was studied and the results
