摘    要:如何有效地去除水中的重金属离子的方法已成为当前水处理领域的研究热点。与其他各种处理材料相比较,生物基材料具有可生物降解、原料可再生和环境友好等特性,因而在去除重金属离子方面具有天然的优势。该文综述了典型生物基材料的结构特征及其在去除重金属离子方面的应用,分析了生物基材料处理重金属离子选择性好、去除率高的原因,原因在于生物基材料含有易与金属离子形成特定的络合结构,形成独特的金属配位化合物具有较高的立体选择性;着重探讨了生物基材料的不同改性方法、机理及必要性,展望了生物基材料研究的未来发展方向及前景。

关 键 词:生物基材料  废水  重金属离子  改性  综述

Abstract:The methods of effectively removing heavy metal ions in water have become a current research hotspot. Bio-based material is biodegradable, renewable and environmentally friendly, which has the natural advantage in removing heavy metal ions. The typical structure of bio-based materials and its application in removing heavy metal ions were summarized. Their good selectivity and high removal rate in adsorbing heavy metal ions were analyzed. The reason may be that the bio-based materials contain some special structures which are easy for heavy metal ions to form metal coordination compounds of special complex structures. The different modification methods, mechanism and the necessity of the bio-based materials were discussed.
Keywords:bio-based material  wastewater  heavy metal ion  modification  overview
