摘要
Abstract
Objective:To establish a determination method of Pb, Cd, As, Hg, Cu in Solanum lyratum Thunb.extract by ICP-MS.Methods:The sample was degisted by microwave digestion, using ICP-MS method to determined 5 kinds of element at the same time with using Ge,In,Bi as the internal standard.Results:The standard curve correlation coefficients of determined elements were all greater than 0.999,the average rates of recovery were from 94%to 108%, and the relative standard deviation ( RSD) was from 3.5%to 8.9%.Conclusion:This method is accurate,fast,simple,and it can be used in determination of the residual amount of the heavy metal analysis and harmful elements in solanum lyratum thunb extract.关键词
