摘　　要：为研究促进新型吸附材料的应用推广,选用30个土壤样品,进行质地及酸碱性分析;采用壤土、砂壤土及酸性壤土、碱性壤土对比分析土壤质地、酸碱度对重金属吸附材料对镉、镍元素吸附效果的影响。结果表明:吸附材料在砂壤土中对镉、镍元素吸附效果明显高于在壤土中对镉、镍元素吸附效果;酸性壤土中吸附材料对镉、镍元素吸附效果明显高于在碱性壤土中对镉、镍元素吸附效果。In order to promote the application and promotion of new adsorbent materials,we selected 30 soil samples for texture and acid and alkaline analysis.Comparative analysis of loam,sandy loam,acidic loam and alkaline loam was used to study the influence of soil texture and pH on the adsorption effect of heavy metal to cadmium and nickel.The results showed that the adsorption effect of Cd and Ni in sandy loam was higher than that in loam.The adsorption effect of Cd and Ni on acid soil was higher than that in alkaline soil.
