基于XRF分析的土壤中重金属元素调查
|
Abstract:
本文调查湖南省慕阜山地区稀有金属矿勘查区内土壤重金属含量，使用粉末压片法对收集到的土壤样品进行前处理，使用能量色散X荧光分析仪对采集样品中的Co、Cr、Cu、Mn、Ni、Pb、Zn等元素含量进行测定分析。采用土壤污染累积指数、内梅罗指数、潜在生态风险指数等方法对其土壤环境质量进行评价分析。
The heavy metal content of soil in the rare metal ore exploration area of Mufushan, Hunan Province was investigated. The collected soil samples were pretreated by powder pressing method, and the contents of Co, Cr, Cu, Mn, Ni, Pb, Zn and other elements in the collected samples were determined and analyzed by energy dispersive X-ray fluorescence analyzer. Soil pollution accumulation index, Nemero index and potential ecological risk index were used to evaluate and analyze the soil environmental quality.
