Arsenic removal has become a relevant concern due to the final confirmation of its behaviour as chronic human carcinogen, corresponding to an ever-increasing contamination of water, soil and crops in many parts of the world. Developing easily accessible removal strategies is therefore a primary environmental matter. Chitosan and chitosan derivatives show good adsorption performances against arsenic removal and are considered low cost products, easily obtainable. This review provides a summary of recent advances of the application of these compounds in the area of sorption sciences for arsenate and arsenite removal from water, focusing on equilibrium and kinetic mechanisms.
由于砷最终被确认为慢性人类致癌物，其行为引起了人们的关注，这导致了世界许多地区的水、土壤和农作物受到越来越多的污染。因此，开发易于获取的去除策略是首要的环境问题。壳聚糖及其衍生物对砷的去除具有良好的吸附性能，被认为是低成本、易于获得的产品。本文综述了近年来这些化合物在吸附科学领域中的应用进展，重点介绍了它们用于去除水中砷酸盐和亚砷酸盐的平衡和动力学机制。
