壳聚糖基吸附材料的制备及其吸附去除水中污染物的研究进展
Research Progress on Preparation of Chitosan-based Adsorbents and Their Applications Towards Adsorptive Removal of Pollutants From Water
摘要
Abstract
Chitosan is the only amino-rich polysaccharide in nature that has characteristic of cationic polyelectrolyte,showing great attention in removing pollutants from water via adsorption.However,its stability is largely affected by solution pH,and it is necessary to accept modification to obtain stable adsorbents.This review summarized the synthesis of chitosan-based adsorbents i.e.hydrogel,composites and N-doped biochar,including their progress towards the removal of heavy metals and organic pollutants.The main factors in affecting removal ability and mechanisms were emphatically introduced,where challenges faced by chitosan-based adsorbents were also pointed out,associating with future direction.In particular,in-situ construction of N-doped biochar from chitosan not only provides a direction for high-value utilization of shell biomass,but has great potential in removing dye-based organic pollutants.It is necessary to do researches in-depth on chitosan-based N-doped biochar and composites in the field of water treatment.关键词
