摘要
采用聚二甲基二烯丙基氯化铵均聚物 (PDMDAAC)对膨润土进行改性 ,制得阳离子膨润土 ,研究其电动特性及对染料废水的脱色效果 .结果表明 ,与膨润土相比 ,阳离子膨润土的表面电性发生了变化 ;处理染料废水的效果明显提高 ,而且在强酸性和强碱性条件下对染料废水的脱色效果最好 .
PDMDAAC bentonite was synthesized by replacing the metal ions in bentonite with PDMDAAC.The electric characteristic of PDMDAAC bentonite was examined by zeta potential(ZP)measurement.The optical conditions of treating dyeing wastewater with PDMDAAC bentonite were also investigated.The mechanism of decoloring and removing COD were discussed.The result indicated that zeta potential and decoloring performance of PDMDAAC bentonite were greatly increased as compared with unmodified bentonite.In the strong acidity and strong alkalinity wastewater,the removal rates were improved obviously.
