| Abstract: | Ten kinds of trace elements, V, Cr, Co, Ni, Cu, Zn, As, Cd, Sb and Pb in soil were determined by graphite digestion and ICP - MS. The results show that the soil samples can be completely digested by using the graphite digestion, and the measured results of soil sample were in agreement with the certified values. The relative standard deviation were between 0. 5% - 4. 6%. The method has the advantages of safety, less pollution, simple operation with good precision and intelligent. It can be applied to treating large quantities of samples at the same time. |
