绿色改性淀粉絮凝剂的研究与应用

淀粉是一种比较理想的绿色试剂原材料。改性淀粉絮凝剂具有绿色、无毒、价廉、易于生物降解等优点。针对接枝类改性淀粉絮凝剂、离子化改性淀粉絮凝剂如淀粉醚类化合物以及淀粉黄原酸脂类等天然改性淀粉絮凝剂的研究进展及在水处理中的应用进行了综述。指出加强利用我国丰富的淀粉资源,开发出绿色、无毒、高效、价廉的改性淀粉绿色絮凝剂,以满足处理各种废水的不同需要,具有极其重要的现实意义。

Research and Application of Green Modified Starch Flocculant

Starch is a natural green reagents material.The modified starch flocculant has a series of virtues such as green,non-toxicity,low price and biodegradability.The research progress in graft copolymers starch,ionized modified starch such as etherified starch and xanthate modified starch,and theirs application in water treatment were introduced.Ii was pointed out that making full use of resources abundant in starch in our state,a great deal of green highly effective,non-toxic and cheap modified starch will be studied to adapt to all kinds of waste water treatment should be strengthened.
