摘要
文章建立了全自动石墨消解-ICP-MS法测定土壤中Cu、Zn、Pb、Cd、Ni和Cr六种重金属元素的方法。结果表明:该方法适用于土壤中Cu、Zn、Pb、Cd、Ni和Cr六种重金属元素的分析,具有良好的线性和较低的检出限。由于整个消解过程由仪器自动完成,避免了由于人员操作不当带来的实验误差,具有较好的精密度和准确性,尤其适合大批量样品的分析。
The method of determination of six kinds of heavy metal in soil by automatic graphite digestion-ICP-MS was established in the paper. Results shows： The method could be applied to the analysis of six kinds of heavy metal elements Cu, Zn, Pb, Cd, Ni and Cr in soil, it also had good linear correlation coefficient and low MDL. The whole process of digestion was done automatically by the instrument, it could avoid the experimental errors caused by the improper operation of personnel, the method was precise and accurate for the analysis of large quantities of samples.
