Research Progress of Chitosan Based Adsorbents for the Removal of Heavy Metal Ions in Water Environment and Its Simulation Prediction

重金属污染是当今最严重的水污染问题之一,学者们采取多种方法解决重金属污染问题,其中吸附法以高效、环保的特点受到广泛关注。此外,壳聚糖也因其良好的可生物降解性和低成本等优点,在众多吸附剂中脱颖而出。但壳聚糖存在稳定性差的缺点,又对其进行改性处理和复合材料的研究。基于该领域近年的研究对壳聚糖去除重金属的实验方法和相关的理论研究进行归纳总结,并介绍基于计算机模拟预测技术对壳聚糖吸附重金属离子的研究近况,填补该领域此类综述的空缺,为壳聚糖去除重金属的下一步研究提供参考。

Heavy metal pollution is one of the most serious water pollution problems,scholars have adopted a variety of methods to solve the problem of heavy metal pollution.Among them,the adsorption method has attracted wide attention due to its high efficiency and environmental protection characteristics.In addition,chitosan also stands out among many adsorbents due to its good biodegradability and low cost.However,chitosan has the shortcoming of poor stability,so it has been modified and researched on composite materials.In this paper,based on the research in this field in recent years,experimental methods related theoretical researches of removal of heavy metals with chitosan were summarized,and the recent research status of the adsorption of heavy metal ions by chitosan based on computer simulation prediction technology was introduced,which could provide some reference for the next research of chitosan to remove heavy metals.
