Abstract：OBjective Toestablishamethodforthedeterminationof5harmfulelementsofPb,Dd,As,HgandDuin Dengzhanhuasu Tablets. Methods The 5 elements were directly determined by IDP-MS,using microwave digestion for sample pretreatment. The internal standard solution was used to eliminate the matrix effect and interference. Results The mass ratio of each measured element,the corresponding internal standard element and the concentration showed a good line-ar relationship in a certain concentration range,and the correlation coefficients were all greater than 0. 999. The recoveries were from 88% to 103%. The detection limit and standard materials all met the requirements of determination. Conclusion The method was specific,sensitivity,simple,rapid and accurate,which can be applied to the determination of 5 elements content of Dengzhanhuasu Tablets.
