Soil sample was decomposed with three acids, namely, nitric acid, hydrofluoric acid, and sulfuric acid and extracted with aqua regia. Analysis was conducted on the microelement Ag with CCT and ICP-MS methods. The result shows that the correlation coefficient of calibration curve of the element is over 0.999 5, the detection limit of element method is 0.009 μg/g; the precision degree and accu- racy degree of the method is in accordance with the standard values, and remarked recovery rate is 98.0%-108.0% which indicate that the method is prompt, simple and accurate and the determined results are ideal.
