| Abstract: | Lead and chromium were determined by inductively coupled plasma mass spectrometry(ICPMS) after microwave digestion with a mixture of nitric acid and hydrogen peroxide.The relative standard deviation(RSD) is less than 5%(n=10).The method is accurate,simple,sensitive and rapid for determination in laminated film.The uncertainty for the determination of Pb in laminated film by ICP-MS was analyzed as example. |
