摘要
用电感耦合等离子体质谱法（ICP—MS）直接测定三（三苯基膦）氯化铑中铂、钯、金、铱。样品用硝酸和高氯酸溶解，选择适当的同位素，克服测定过程中的质谱干扰，以元素铟做内标，补偿因基体效应和仪器波动的影响。方法加标回收率为93．8％～104．2％，相对标准偏差为1．27％-4．17％。
An ICP- MS method for the determination of Pt,Pd,Au,Irin Chlorotris （triphenylphosphine） rhodium was described in this paper. The sample was dissolved in Nitric acid and Perchloric acid , selection of proper isotopes of the elements to be determined made it possible to overcome the mass spectrometric peak interference to a great extent. The use of In as internal standards, the influences due to matrix effect and fluctuation of the instrument were compensated effectively. Recoveries obtained by standard addition method were in the range from 93. 8% to 104. 2% and RSD calculated from the results of determination were in the range of 1.27% to 4. 17%.
