| Abstract: | A method for the simultaneous determination of Pb,As,Cu,Cd in master batch by ICP-MS microwave digestion was studied.This method has simple operation,rapid analysis,highly accurate,reliable,and can be applied in simultaneous determination of heavy metal elements in master batch.Recoveries of the elements from the spiked master batch sample were in the range of 95.2%~101.8%,and the RSD was less than 3%.The results obtained agreed quite well with the certified values. |
