摘　　要：壳聚糖优异的无毒性、生物相容性、由于丰富的官能团而具备的较强吸附性以及成本低廉的特点使其有望成为潜在的优良吸附材料。但未改性的壳聚糖在酸性条件下易发生水解,吸附性能弱,通过与其他材料复合可以增加壳聚糖的吸附位点、力学强度,复合后的材料能够适应不同条件下的废水吸附环境。本文论述了当今热点的壳聚糖/磁性纳米颗粒(CS/MNPs)、壳聚糖/氧化石墨烯(CS/GO)、壳聚糖/粘土矿物(CS/CM)、壳聚糖/生物炭(CS/BC)等壳聚糖/无机复合吸附剂特性和优势进行归纳总结,并对这几种复合材料对常见重金属的去除现状进行了综述。Chitosan's excellent non-toxicity,biocompatibility,strong adsorption properties due to its rich functional groups and low cost make it expected to be a potential excellent adsorption material.However,unmodified chitosan is prone to hydrolysis and weak adsorption performance under acidic conditions,and the adsorption sites and mechanical strength of chitosan can be increased by compositing with other materials,and the composite material can be adapted to the adsorption environment of wastewater under different conditions.This paper discusses the properties and advantages of chitosan/inorganic composite adsorbents such as Chitosan/Magnetic Nanoparticles(CS/MNPs),Chitosan/Graphene Oxide(CS/GO),Chitosan/Clay Minerals(CS/CM),and Chitosan/Biochar(CS/BC),which are hotspots nowadays,and summarised the characteristics and advantages of chitosan/inorganic composite adsorbents,as well as the current status of these composites for the removal of common heavy metals.
