【摘要】 随着工业的快速发展,大量重金属镉进入土壤,致使土壤中重金属镉超标,从而导致农作物中镉含量超标,严重危害人们的身体健康。因此,对重金属镉污染土壤进行治理和修复已成为目前重要的环境保护任务。本文首先制备了一种新型重金属镉污染土壤修复剂,然后研究了其对重金属镉污染土壤的修复效果。结果表明,制备的新型镉污染土壤修复剂对污染土壤中重金属镉具有良好的修复效果,在最佳的试验条件下,污染土壤中镉的去除率可以达到37.72%。更多还原

【Abstract】 With the rapid development of industry, a large number of heavy metal cadmium enters the soil, which leads to the excessive content of heavy metal cadmium in the soil and the excessive content of cadmium in the crops. It could seriously endanger the people′ s health. Therefore, the remediation of heavy metal cadmium contaminated soil has become an important environmental protection task. In this paper, a new remediation agent for heavy metal cadmium contaminated soil was prepared,and then its remediation effect on heavy metal cadmium contaminated soil was studied. The results showed that the new remediation agent had a good remediation effect on the heavy metal cadmium in the polluted soil. Under the best experimental conditions, the removal rate of cadmium in contaminated soil could reach 37.72%.更多还原
