Chinese Abstract

研究了不同消解方法對玩具塗料中As,Ba,Cd,Cr,Pb,Sb,Se有害重金屬元素總含量測定結果的影響,確定以NHO3+酒石酸+H3PO4溶樣並用全譜直讀等離子體光譜儀同時測定其八種有害重金屬元素總含量的方法。加標回收試驗及模擬樣品測定結果表明,該方法快速、凖確、可靠,且能滿足玩具安全標凖對各元素的檢出限要求,適於進出口玩具的日常檢驗。

English 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.
