| 摘 要： | 将壳聚糖、阳离子淀粉和二甲基二烯丙基氯化铵(DMDAAC)进行三元接枝共聚,制备了三元接枝改性壳聚糖(CTS-DMDAAC-CS),通过红外光谱和扫描电镜对其结构进行了表征.并且将三元接枝改性壳聚糖与凹凸棒土进行优化复配,对油漆废水进行了絮凝实验,得出了当pH=12,沉降时间为20 min,复合絮凝剂投加量为0.2 g,三元接枝共聚物:凹凸棒土=1:10时,该复合絮凝剂对油漆去除率最佳能够达到89.3%,并且絮凝效果好,是一种新型绿色环保的有机-无机复合絮凝剂. |

| Abstract: | The modified chitosan (CTS-DMDAAC-CS) was synthesized by chitosan, cationic starch and dimethyl diallyl ammonium chloride (DMDAAC). And it was characterized by scanning electro-microscope and infrared spectroscopy.The combination of modified chitosan and attapulgite for flocculation was investigated. The removal rate of the paint could achieve 89.3% with pH of 12, depositing time of 20 min, 1:10 CTS-DMDAAC-CS/attapulgite weight ratio, 0.2 g composited flocculant. The complex of modified chitosan and attapulgite was a novel and environment-friendly organic-inorganic flocculant. |
| Keywords: | chitosan modified chitosan attapulgite flocculation paint wastewater |
