摘　　要：采用阳离子修饰以及与阳离子淀粉混合的方式对膨润土进行改性,发现具有苯酚吸附增效的作用,DT修饰的膨润土更具优势。而在对罗丹明进行脱色实验中,所采取的3种系统均对染料脱色有显著增效作用,并且相互之间比较没有显著差异,在综合考虑到成本以及对环境的友好性等多方面因素后,本研究结果表明阳离子淀粉混合膨润土体系对于处理简单污染物更具优势。Cationic modification and cationic starch mixing were used to modify bentonite, and it was found that it had the synergistic effect of phenol adsorption, and DT modified bentonite had more advantages. In the decolorization experiment of rhodamine, the three systems had significant synergistic effect on the decolorization of the dye, and there was no significant difference between them. Taking into account the cost and the environmental friendliness, the results of this study showed that the cationic starch mixed bentonite system had more advantages for the treatment of simple pollutants.
