壳聚糖复合物对重金属离子的吸附作用

Adsorption of Heavy Metal Ions by Chitosan Complexes

壳聚糖复合物是壳聚糖与其它无机、有机物质经物理或化学方法合成的复合吸附剂。复合后改善了吸附剂的物理性能,提高了吸附能力,增加重复使用次数。因此壳聚糖复合物在工业废水处理领域得到广泛的应用。本文综述了不同壳聚糖复合物对重金属离子的吸附作用,对壳聚糖复合物的研究方向进行了展望。

Chitosan complex is a composite adsorbent of chitosan and other inorganic and organic materials synthesized by physical or chemical methods. After recombination, the physical properties of the adsorbent were improved, the adsorption capacity was improved,and the times of repeated use were increased. Therefore, chitosan complex has been widely used in industrial wastewater treatment. In this paper, the adsorption of heavy metal ions by different chitosan complexes was reviewed, and the research direction of chitosan complexes was prospected.
