| 摘 要： | 受到镉污染的农作物会危害人类的健康。农作物的镉污染是土壤中的镉迁移造成的。通过等温吸附试验和盆栽试验，研究了凹凸棒石对Cd^2 的吸附及对镉污染土壤上玉米生长的影响。试验表明，凹凸棒石对Cd^2 有很好的吸附作用，在镉污染土壤中添加少量的凹凸棒石可使玉米的镉中毒程度降低，促进玉米生长。因此，可利用凹凸棒石进行镉污染土壤的原位修复，达到治理土壤污染的目的。

| Abstract: | The crops subjected to Cd-pollution poses a threat to the health of people. The Cd-pollution is mainly produced by the transfer of Cd in soil. The adsorption of cadmium ions in attapulgite is studied by isothermal adsorption method, and the effect of attapulgite on the growth of maize in cadmium contaminated soil is also investigated by pot experiment. The results show that attapulgite has a high affinity for cadmium ions, and can prevent the toxication of maize and enhance the growth of maize by adding a little of attapulgite in cadmium contaminated soil. Therefore, attapulgite can be used to remedy cadmium-contaminated soil on site, and the objective of improving contaminated soil can be realized. |
