摘要
对玩具、铅笔中可溶性砷、锑、硒的形态分析方法进行了研究,对原子荧光光谱法测定不同价态砷、锑、硒的方法进行了优化,建立了砷、锑、硒的原子荧光光谱形态分析方法。该方法样品加标回收率为82.0%~110.0%,测定结果的相对标准偏差为1.35%~2.22%(n=10)。
Speciation methods of As, Sb, Se in toys and pencils were investigated, and measuring conditions were optimized. The methods for testing As, Sb, Se of different valency by atomic fluorescence spectrometer (AFS) were optimized and the speciation methods of AFS were presented. The recoveries of arsenic, stibium, selenium in samples were 82.0 % - 110.0 %, and RSD for the determination results were 1.35 % -2.22 % (n = 10).
