XRF光谱法研究城市工业区的土壤环境污染

利用X射线荧光光谱法(XRF)对某城市工业区周围的土壤环境进行了研究.根据对土壤中Pb、Zn、Cu、Cr、Ni、Mn、S、N、P 9种元素含量,土壤的pH值以及TOC的测定和利用内梅罗综合污染评价指数法对重金属污染评价的结果,表明工业区电池厂的生产活动是土壤环境污染的主要因素,建立了重金属Pb与土壤性质间的回归预测模型,提出了造成土壤环境污染的原因.且XRE法是对土壤重金属检测和污染评价的快速有效的方法.

Study on the Soil Environment Pollution in City Industry Zone by XRF Method

Impact of manufacturing activities of a battery garage in the industrial zone of a city on soil environment therein was investigated. Concentrations of Pb, Zn, Cu, Cr, Ni, Mn, S, N and P in the soil were determined with the XRF method and values of pH and TOC were measured. And then environmental impact of heavy metal pollution on city soil environment was evaluated with the Nemero Index Method. Results showed that the prospect of heavy metal pollution is considerably serious, and the activities of the battery garage the main pollution source. A regress model was established for relationship between Pb and soil properties. The XRF method is proved to be a fast, effective analytic method.
