【摘要】 淀粉来源丰富、可再生、价格低廉,是比较理想的环保试剂原料。淀粉衍生物絮凝剂具有选择性大、无毒、可生物降解等特点。针对淀粉的这些特点,制备价廉、絮凝效果好的改性淀粉絮凝剂,对开发环保型絮凝剂具有现实意义。介绍了利用淀粉为基材,接枝丙烯酰胺制备环保型高分子絮凝剂的方法。更多还原

【Abstract】 Starch is a natural green reagents material which is rich,renewable and cheap.The modified starch flocculant has a series of advantages such as wide selection possibility,non-toxicity,biological degradation,etc.There is practical significance for developing green flocculant to prepare modified starch flocculant with low cost and effective flocculation,in view of starch these characteristics.The green polymeric flocculant is prepared by starch grafting acrylamide in the research.更多还原
