摘要
与传统水处理药剂相比,改性淀粉作为絮凝剂和重金属捕集剂,具有成本低廉、可生物降解、毒性小、可再生等优点。按照反应类型,阐述了近年来酯化、醚化、接枝、氧化等几类改性淀粉作为重金属捕集剂的研究进展、应用现状及优缺点,同时对淀粉基重金属捕集剂的前景及发展趋势进行了展望。
Compared with traditional water treatment agents,modified starch used as flocculant and heavy metal chelating agent has the advantages of low cost,biodegradability,low toxicity and renewable.According to the reaction types,the research progress,application status,advantages and disadvantages of esterification,etherification,grafting,oxidation and other modified starches as heavy metal chelating agents in recent years were reviewed.At the same time,the prospect and development trend of starch based heavy metal chelating agents were prospected.
