摘　　要：木质纤维素废弃物作为生物吸附剂能有效地去除废水中毒性的重金属离子。本文综述了各种不同低成本的农产品及食用农产品产生的木质纤维素废弃物作为生物吸附剂的研究进展,对目前各种廉价的的生物吸附剂的吸附机理及化学改性和制备方法进行了探讨,指出了金属离子初始浓度、温度、吸附剂粒径、吸附剂剂量、吸附时间、溶液的pH值等吸附影响因素对吸附剂吸附重金属的影响。介绍了蔗渣、秸秆、稻壳、锯末、橙皮、橘子皮、花生壳等生物吸附剂对重金属废水的处理现状,同时对加强吸附剂的改性及吸附机理研究进行了展望。Lignocellulose wastes as a biological adsorbents can effectively remove the toxicity of heavy metal ions wastewater. This paper reviews the Progress of various cost biosorbent from the waste of agricultural products and edible agricultural products. Discussed the adsorption mechanism, chemical modification and preparation methods of variety adsorbent of natural agricultural. The influencing factors such as the initial metal ion concentration, temperature, adsorbent particle size, adsorbent dosage, adsorption time, the pH value of solution were analyzed on adsorption. Introduced the status quo of biological adsorbents in the wastewater treatment such as bagasse, straw, rice husk, sawdust, orange peel, orange peel, peanut shells et al. At the same time,the research trend to the modified adsorbents and adsorption mechanism in the future was discussed as well.
