Abstract

A method was developed for the determination of the soluble Pb, Cd, As and Hg in the polymer of food contact materials by inductively coupled plasma-mass spectrometry (ICP-MS).Samples were extracted by 0.07 mol/L hydrochloric acid solution, and then analyzed with ICP-MS.Within the range of 0.5 μg/L～100 μg/L, recoveries and RSD were 88.6%～98.3% and 1.8%～5.1%, respectively.
