摘要
磁性壳聚糖具有吸附性能强,廉价和易回收等优点,论文探讨了磁性壳聚糖水处理机理,综述了磁性壳聚糖在去除金属离子,处理印染废水、含酚废水、造纸废水和食品废水等领域的研究进展;比较了磁性壳聚糖与其他改性壳聚糖和传统絮凝剂的性能,提出磁性壳聚糖的优越性;同时对磁性壳聚糖的研究开发提出了建议。
Magnetic chitosan has advantages such as good adsorption capacities, low-cost and easily recyclable. The mechanism of treating water with magnetic chitosan was discussed and a summary was made on the study progress of application of magnetic chitosan in fields such as metal ions removal, textile dyeing wastewater treatment, phenol-containing wastewater treatment, paper making wastewater treatment and food wastewater treatment. Compare magnetic chitosan with other modified ehitosans and conventional flocculants , magnetic chitosan shows obvious advantage. Moreover, several advices are given to the research and development of this new water treatment agent.
