| 摘 要： | 评述了近年来国内外利用廉价农林废弃物去除废水重金属的研究进展.重点论述了化学改性处理的农林废弃物对重金属离子的吸附性能,并详细比较了改性前后及各种改性方法的吸附效率.改性处理明显提高了农林废弃物的吸附性能,一些改性的农林废弃物吸附剂对某些重金属离子具有良好的吸附性能,显示出广阔的应用前景.但在今后的研究中还应强化改性农林废弃物吸附剂表面结构表征、吸附作用机理和动力学的研究,开发新型高效的改性再生方法,并对废水处理成本进行详细评估.

| Abstract: | The application of low-cost adsorbents derived from agricultural and forest wastes for the removal of heavy metal ions from metal-contaminated wastewater has been reviewed. The discussion is focused on the adsorption capacities for heavy metal ions by chemically modified agricultural and forest wastes. A comparison of adsorption efficiency between chemically modified and unmodified adsorbents is also reported. On the whole,it can be said that chemically modified agricultural and forest wastes exhibit higher... |
