摘　　要：采用FeCl_(3)·6H_(2)O溶液对累托石粘土进行改性,制得铁改性累托石粘土(IMR),研究了IMR对水溶液中Sb(Ⅲ)的吸附效果,探讨了铁改性累托石粘土载铁量、吸附时间、锑源溶液浓度与吸附效果的关系。实验结果表明载铁量是影响吸附效果的主要因素,IMR对Sb(Ⅲ)的最大吸附量为14.25mg/g。Modifying rectorite with FeCl_(3)·6H_(2)O solution obtained iron modified rectorite(IMR),the adsorption effect on Sb(Ⅲ)of IMR were studied.Relationship between the iron content of IMR,the adsorption time,the initial concentration of Sb(Ⅲ)solution and the adsorption effect were discussed.The results show that the iron content is main influencing factor,and maximum adsorption capacity of IMR on Sb(Ⅲ)is 14.25mg/g.
