摘要
Abstract
A simultaneous determination method for arsenic (As),lead (Pb)and cadmium (Cd)in cosmetics by inductively coupled plasma-optical emission spectrometry (ICP-OES)was established. The sample was digested by nitric acid - hydrogen peroxide under the assistance of microwave irradiation. Meanwhile,the conditions of ICP-OES were optimized. The method under optimized conditions shows good linearity with the mass concentrations of the three heavy metal ions in range of 0. 05 -1. 20 mg/L. The corresponding linear correlation coefficients for the heavy metals are all 0. 9998 with the spiked recoveries ranging within 90. 7% -108. 6%,and the relative standard deviation within 0. 44%-4. 59%(n =6 ). The limits of detection and quantification of As,Pb and Cd are 0. 63,0. 30,0. 015 mg/kg and 2. 1,1. 0,0. 05 mg/kg,respectively.关键词
