目前重金属水污染问题受到人们极大的关注，花生壳吸附处理重金属废水具有广阔应用前景。文章结合目前国内外研究进展，综述了活化改性、酸甲醛改性、酸改性、高锰酸钾改性及生物改性等花生壳改性方法，探讨溶液 pH 值、吸附温度、吸附剂用量、吸附时间、重金属离子初始浓度等因素对吸附过程的影响，分析了改性花生壳吸附重金属离子的吸附机理、吸附模型及动力学热力学参数，为花生壳资源化利用与农业废弃物处理重金属废水方面的研究提供理论参考。

currently,water pollution by heavy metals has attracted much attention,and using peanut shell to adsorb heavy metals from wastewater is prospective in application. In this paper,we have re-viewed the modification methods for peanut shell,including activation modification,acid formalde-hyde,acid,and potassium permanganate and biological modification,based on relevant research progress both at home and abroad. We have also discussed factors affecting the adsorption process such as solution pH,adsorption temperature,adsorbent dosage,adsorption time,and initial concen-tration of heavy metal ions,and analyzed adsorption mechanism,adsorption model,adsorption kinet-ics and thermodynamic parameters. The results of the study can serve as theoretical reference for the further research on recycling of peanut shell and on the treatment of heavy metals polluted water using agricultural wastes.
