絮凝法提纯钙基膨润土的研究

The study of purifying calcium-based bentonite

用无机、有机絮凝剂和自制醋酸甲壳素溶液 ,分别对膨润土浆液进行絮凝提纯 ,结果表明 :自制醋酸甲壳素溶液对膨润土的提纯效果比无机、有机絮凝剂好 ,提纯后的膨润土白度达到 78.6% ,蒙脱石含量达90 .1 % .

the thick liquid of bentonite is purified respectively by flocculanting method with inorganic,organic flocculant and the aqueous solution containing acetic acid aftr immersing the shell shrimp.The result obtained shows that:the effect of purifying with this solution is better than with inorganic and organic flocculant,the white extent of the purified bentonite is to 78.6%,the concent of Al 2O 3·SiO 2·3H 2O is to 90.1%.
