铅污染土壤的净化用EDTA螯合剂

作者(年代):Kabilan N和Muttharam M

土壤是一种重要的自然资源。污染和土壤污染在当今是非常常见的场景。土壤中铅污染是一个严重的风险构成伟大的线程环境可持续性。铅污染土壤中可能会影响动物和人类的健康,当他们吃植物或动物,自己受到土壤污染的影响。铅污染土壤的修复是至关重要的。受污染的土壤样本来自Perungudi垃圾堆积场,市政固体废物垃圾场。重金属量化技术使用ICP-AEP(电感耦合等离子体原子发射光谱仪)实验室。浓度不同的金属在土壤样品被发现。在目前的研究中,铅的浓度就与印度相比堆肥标准。结果显示浓度高于他的监管限制。 Therefore, the samples were subjected to decontamination technique. Decontamination technique was done using ethylenediaminetetraacetic acid EDTA. After applying decontamination technique, the lead concentration of the decontaminated samples was analyzed again using ICP-AES. Results showed the lead concentration to be below the Indian Compost Standards. The average efficiency of the EDTA technique was found to be 77%. This showed that the EDTA technique applied to be an effective.
