摘　　要：为确定重金属吸附材料最佳加入量在不同质地土壤中的吸附效果,通过对比分析,探讨了不同用量重金属吸附材料在不同质地(酸性壤土、碱性壤土、砂壤土)不同镉镍污染土壤中的吸附效果。结果表明:重金属吸附材料在酸性壤土、碱性壤土、砂壤土中对镉元素吸附的最佳加入量均为土壤质量的0.9%,镍元素吸附的最佳加入量均为土壤质量的1.2%;吸附材料对不同质地土壤中镉、镍的吸附效果不同,砂壤土明显高于壤土。In order to determine the best adsorption effect of heavy metal adsorption materials in different texture soils,comparative analysis was conducted.The adsorption effect of heavy metal adsorption materials in different materials（acidic loam,alkaline loam,sandy loam）with different cadmium and nickel contamination was discussed.The results showed that the best addition of cadmium in acid loam,alkaline loam and sandy loam was0.9% of soil quality,and the best addition of nickel was 1.2% of soil quality.The adsorption of cadmium and nickel in different soils was different,and the sand soil was significantly higher than the loam soil.
