摘要
以天然高分子植物粉 F691为原料 ,通过羧甲基化、接枝共聚和曼尼期 ( Mannich)三步反应合成出两性天然高分子改性絮凝剂 ( CGAAC)。研究了阴 /阳取代度、接枝率等结构因素对 CGAAC絮凝性能的影响 ;并将 CGAAC对高岭土的絮凝性能与阴离子絮凝剂 CGA和阳离子絮凝剂 PAM-C进行了对比 ,实验结果表明 :该絮凝剂具有最佳用量范围较宽、p
In this paper the natural wood powder F691 was modified by carboxymethyl reaction,grafting reaction and Mannich reaction to prepare a new amphoteric flocculant(CGAAC),the optimal structure conditions for the preparation of CGAAC were determined.The flocculation properties of CGAAC toward the water of kaolinite were also studied, the experimental results showed that CGAAC have wider optimal dosage and pH value for flocculation.
