The ashing temperature could be increased and some interferences from hy-drochloric acid,molybdenum and boron could be eliminated in title method by using Pd andNias a matrix modifier.The method can be used directly for lead and antimony analysis inhigh temperature nickel-alloy without preseparation of the matrix. The characteristic mass is28pg and 26pg, the detection limit is 0.13μg/g and 0.23μg/g,the recovery is 94%~103%and 95%~110%,the relative standard deviation is 6.4%~7.6%and 4.7%~7.5%for leadand antimony,respectively。
