ICP-AES Simultaneous Determination of Migration Amounts of As, Ba, Cd, Co, Cr, Hg, Ni, Pb, Sb and Se from Imitated Decorations

Sample of imitated decoration was extracted with acidic sudor of simulated body environment for 60 min, and the contents of As, Ba, Cd, Co, Cr, Hg, Ni, Pb, Sb and Se were determined by ICP-AES. Wavelengths of 193.759, 233.527, 214.438, 228.616, 267.716, 194.227, 232.003, 220.353, 206.833 and 196.090 nm were selected as analytical lines for the 10 metal elements respectively. Values of detection limits (3sb/k) and lower limits of determination (15sb/k) were found in ranges of 0.002-0.06 mg·L-1 and 0.01-0.3 mg·L-1 respectively. The proposed method was used in the analysis of imitated decorations, giving values of recovery and RSD′s (n=7) in the ranges of 88.0%-100% and 3.1%-9.8% respectively.
