摘要:
为了研究重金属钝化材料，以甘肃凹凸棒粘土为基础材料进行碱改性制备土壤重金属钝化材料，进行钝化实验和植物富集实验后对土壤中重金属Cu、Zn的酸溶态含量和玉米对Cu、Zn的富集量进行测定。结果表明：凹凸棒粘土与生石灰的质量比为3∶1、搅拌时间为72 h时凹凸棒粘土对土壤中Cu的钝化容量最大，玉米对Cu富集量最低；质量比为4∶1时，搅拌时间为48 h和72 h时Zn的钝化容量显著高于其它改性条件下的钝化容量，玉米对Zn富集量显著低于其它改性条件下的富集量。
Abstract:
The passivation effects of different alkaline chelated modified attapulgite and different application amounts on Cu,Zn in soil were studied by laboratory simulation test.The results showed that when the mass ratio of attapulgite to quicklime is 3∶1 and the stirring time is 72 h,the attapulgite had the largest capacity for passivation of Cu in soil,and the concentration of Cu in maize was the lowest.When the mass ratio is 4∶1 and when the mixing time is 48 h and 72 h,the passivation capacity of Zn in soil was significantly higher than that in other modified conditions,and the concentration of Zn in maize was significantly lower than that in other modified conditions.
