Abstract

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.

摘要

采用电感耦合等离子体发射光谱法（ICP - AES）同时测定玩具涂料中砷、钡、镉、铬、汞、铅、硒、锑的总含量。已开发出这些材料与不同酸混合物的消解程序。样品用硝酸、酒石酸和少量磷酸的混合酸溶解。研究了基体元素的影响并考察了最佳实验条件。该方法的回收率在99%至109%之间。相对标准偏差（RSD）在1.5%以内。所提出的方法简单、快速，可用于玩具的日常检测。
