摘要
综述了壳聚糖及其衍生物在废水治理方面除汞的最新进展,介绍了壳聚糖及其衍生物在不同条件下的吸附能力。其中,壳聚糖对Hg(Ⅱ)离子的吸附能力在430～1 127mg/g之间,而壳聚糖衍生物能增加吸附的稳定性和选择性。此外,磁性吸附技术是近年来研究的热点。
The recent development in removing Hg （ Ⅱ ） from waste water by chitosan and its derivatives is summarized, and the adsorption capacity of chitosan and its derivatives under different experimental conditions is introduced. The adsorption capacity of chitosan for Hg （Ⅱ ） ions ranging from 430 to 1 127 mg/g, while the chitosan derivatives can increase the stability and selectivity of adsorption. In addition, the magnetic adsorption technology has attracted many researchers.
