In order to decomposes the sample completely and eliminate the impact of carbon, preparation of sample, carbon removed by H2SO4+HNO3 smoking, formic acid reduction, dissolved by aqua regia. determine palladium content in the selected conditions of ICP-AES. The recovery ranged from 97.0% to 101.8%, the relative standard deviation (n=6) is less than 3%, determination result of the method and method of ignition reduction and fire assay is consistent, the method is simple and fast, environmental protection, conservation, and accurate.
