摘　　要：水体中的六价铬已经成为一大环境危害,人们十分重视控制环境中含六价铬废水的排放。经济上的可行性使得低成本吸附剂在环境污染治理中的重要性日益加强。综述了生物材料及其改良产物在含铬废水处理中的应用研究进展,分析了生物吸附处理含铬废水的机理、影响因素及改良方法,指出了使用低成本生物吸附法处理含铬废水的发展方向。Nowadays, with the exponentially increasing population the need for controlling hexavalent chromium emissions into the environment is even more pronounced. According to the economic feasibility, low-cost biosorbents are gained more attention. Application progress of biosorbents in purification ofwastewater containing chromium compounds was reviewed and its mechanisms as well as factors associated with absorption performances and ways to improvements of biosorbents were analyzed. The future prospective for the technology development was given.
