研究了采用两性表面修饰剂十二烷基二甲基甜菜碱(BS-12)和阳离子表面修饰剂十六烷基三甲基溴化铵(CTMAB)复配修饰填土后对苯酚的吸附反应和热力学特征,并探讨其吸附机理.结果表明,复配修饰后的土样对苯酚的吸附能力明显增强.20℃时表现为CK(原土)<50BS(50%BS-12)<100BS(100%BS-12)<50BS+25CT(50%BS-12+25%CTMAB)<100BS+25CT(100%BS-12+25%CTMAB)<50BS+50CT(50%BS-12+50%CTMAB)<100BS+50CT(100%BS-12+50%CTMAB),40℃时表现为CK(原土)<50BS(50%BS-12)<100BS(100%BS-12)<50BS+25CT(50%BS-12+25%CTMAB)<50BS+50CT(50%BS-12+50%CTMAB)<100BS+25CT(100%BS-12+25%CTMAB)<100BS+50CT(100%BS-12+50%CTMAB).其吸附等温线可用Henry模型描述.供试土样对苯酚的吸附呈现放热焓减反应特征,属于焓减控制的自发性过程.
