| 摘 要： | 水体中的重金属污染物不能被微生物降解,并且环境中只要存在微量的重金属即可产生毒性效应。因此,研发新材料去除水体中重金属离子受到了广泛的关注。利用绿色、经济、产量丰富的壳聚糖为原料,以物理和化学改性方法为手段制备移除水体中重金属离子的壳聚糖基吸附材料是当今研究热点。本文以壳聚糖基材料的制备方法为主线,概括总结了壳聚糖的改性方法及其衍生物对重金属离子吸附行为的研究进展,展望了壳聚糖基材料在重金属废水处理方面的未来研究方向及前景。

| Abstract: | In aqueous environments, heavy metal pollutants cannot be degraded by microorganism, and trace amounts of them can generate toxic effects. Therefore, many studies have focused on the development of novel materials for the removal of heavy metal ions from aqueous environments. In recent years, chitosan has been used as a raw material to chemically or physically prepare adsorption materials because of its eco-friendliness, low cost, and resource productivity. For adsorption materials prepared using chitosan-based materials in the main line, this paper summarizes the progress on the chitosan modification methods and the adsorption behavior of the chitosan derivatives to the heavy metal ions. The future study directions and prospects of chitosan-based adsorption materials for the removal of heavy metal ions are also discussed. |
