| 摘 要： | 采用与传统方法不同的超声化学法,用二甲亚砜(DMSO)对高岭土进行插层,大大缩短了处理时间,而且达到了较理想的插层效果。采用X -衍射研究插层间距,发现硅酸盐片层间距从0.714 nm增加至1.123 nm左右,插层率为90.9%,并对不同超声条件对插层率的影响进行了探讨。同时用FT-IR和TG/DTA等方法对插层机理进行了分析和研究。

| Abstract: | In order to improve the efficiency of kaolinite-DMSO intercalation, sonochemistry technique has been used. Experimental results indicated that the high intercalation effect was obtained in a shorten time. The XRD analysis showed that the interlayer spacing was increased from 0.714 nm to 1.123 nm and the displacement ratio reached up to 90.9%. At the same time, the intereaction mechanism between kaolinite and DMSO was investigated by means of SEM, FT-IR, high temperature DTA and TG analysis. |
