The paper points out the best adsorption condition: the containing water rate in the soil is 20%, pH value is 5, addition quantum of modiifed ifbrin of magnetism sphericity is 7.5%, adsorption time is at 10d, the removal rate of CD in the poluted soil reaches at 75.01%.%通过添加凹土和硅溶胶，结合成型技术制备粒径为3～5mm材料，应用于土壤中镉污染的修复，最佳吸附条件：土壤含水率为20%，pH值为5，磁性球形改性纤维素的添加量为7.5%，吸附时间10d，对污染土壤中Cd的去除率达75.01%。
