[Simultaneous determination of the total content of As, Ba, Cd, Cr, Hg, Pb, Se, Sb in paint coating on toys by ICP-AES].
ICP-AES was used for the simultaneous determination of the total content of As, Ba, Cd, Cr, Hg, Pb, Se, Sb in paint coating on toys. Digestion procedures of these materials with different acid mixtures have been developed. The sample was dissvolved in the acid mixture of nitric acid, tartaric acid, and a little phosphoric acid. The matrix elements effect was studied and the preferable experimental conditions were investigated. The recovery rates of this procedure were between 99% and 109%. The RSD was within 1.5%. The proposed method was simple, rapid and can be used in daily inspection of toys.
