改性壳聚糖材料在含重金属废水处理中的应用研究进展
Research Progress on Modified Chitosan Materials in Heavy Metal Waste-water Treatment
摘要
Abstract
Contaminated waste water by heavy metals endangers the ecosystem and human ' s health. Therefore, the research on the treatment of heavy metal waste -water has become urgent.In recent years, scholars at home and abroad pay great attention to the study of modified chitosan for treatment of heavy metal waste-water.The modified chitosan as a new, efficient, recyclable and reusable adsorption material is very effective in the treatment of heavy metal waste -water.By improving the preparation method and making it suitable for practical industrialization , the preparation of highly selective, high adsorption capacity and highly efficient modified chitosan will become the main researching focus in the future .The physical and chemical modification methods of chitosan were described based on the new research at home and abroad, the properties and characteristics of chitosan and modified chitosan were systematically introduced, the chemical modification methods of cross -linking, grafting and composite modification research work were particularly presented , and the application of chitosan and its modification in heavy metal waste-water treatment were also expounded .The adsorption mechanism and regeneration recycle rule of those materials have been deeply explored so we can conclude that the modification chitosan materials can be highly selected and highly efficient for adsorbing heavy metal ions , and have the "one-to-many"adsorption.关键词
