摘要
以信阳上天梯矿膨润土为原料,经钠化处理后,用溴代十六烷基三甲胺进行有机包覆,制得憎水亲油性有机膨润土;研究了有机膨润土对水中苯胺的吸附作用,探讨了吸附时间、介质pH值、苯胺浓度等因素对吸附的影响,以及有机膨润土对苯胺的吸附机理。
Organobentonite was prepared through taking Shangtianti catrobentonite,Xinyang,as raw material,sodium version and treating with cetyltrimethyl ammonium bromide (CTMAB).Adsorption of the organobentonite for aniline was researched.The mechanism of adsorption and the factors influencing the adsorption are discussed.Experimental results indicated that at ambient temperature,pH2 and adsorption time of 1h,adsorption rate of aniline by the organobentonite is 82.47%.The logarithm adsorption isotherm of organobentonite for aniline accorded with the Freundlich equation.
