ABSTRACT
Objective To establish an ICP-MS method for the determination of heavy metals,including copper(Cu),arsenium(As),cadmium(Cd) and plumbum(Pb),in five kinds of Chinese medicinal material.Methods The samples were digested by closed-vessel microwave.The four heavy metals were directly analyzed by ICP-MS,with elements 72Ge,115In,and 209Bi as the internal standards.Results For all of the analyzed heavy metals,the correlative coefficient of the calibration curves was in the range of 0.999 5~ 0.999 7.The recovery rates were in the range of 92.3 % ~ 108.0 %,and RSD were in the range of 2.4 % ~ 5.8 %.Conclusion The method is convenient,rapid,accurate and can be applied to determine four heavy metals,including Cu,As,Cd and Pb,in Chinese medicinal material.
