| 摘 要： | 用十六烷基三甲基氯化铵对钠基膨润土进行了改性,研究了土样用量、吸附时间、溶液pH值对Zn2 吸附的影响,对比研究了无机膨润土和有机改性膨润土吸附Zn2 的结果.结果表明:无机膨润土和有机改性膨润土均能较好地吸附Zn2 ,且有机改性膨润土吸附的能力更强;溶液pH值对无机膨润土和有机改性膨润土吸附Zn2 的影响不同.

| Abstract: | The Na-bentonite was modified with cetyltrimethyl ammonium chloride(CTAC),and the effects(amount of bentonite,adsorption time,pH value of the solution) on adsorption of Zn2 were studied.Meanwhile,the adsorption results of Zn2 in inorganic bentonite and organic modified bentonite were compared.It was indicated that the bentonites were good adsorbent materials for Zn2 ,but the adsorption capability of organic modified bentonite was stronger than that of inorganic one.Furthermore,the effects of pH value on the Zn2 adsorption in the bentonites were different. |
