Abstract:A method for the simultaneous determination of the contents of eight elements(Pb, Cd, As, Hg, Ba, Cr, Sb, Se) in pearlescent pigment were established by industively coupled plasma-mass spectrometry (ICP-MS) with microwave digestion. Good linearity of the calibration curves was obtained for all target elements(r= 0. 9991-1. 0000). Detection limits for these eight elements were in tlm range of 1.17--30.59μg/L. The recoveries were carried out by standard addition method and recovery was 94. 5%-101. 7% for elements concentration between 1. 0mg/kg and 10mg/kg. The pearlescent pigment sample was measured parallel five times and the RSD was lower than or equal to 2.03% ,and the method had good precise and accuracy. The technique is applied for the quality control and safety evaluation of pearlescent pigment.
Keywords:Pearleseent Pigment  Microwave Digestion  ICP-MS
