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。试验结果表明,该方法准确可靠,样品的加标回收率为82.0%￣110.0%,方法的变异系数为1.35-2.22%。
Speciation methods of As Sb Se in toys and pencils were investigated. The methods determinating As Sb Se of different valency by Atomic Fluorescence Spectrometer（AFS） were optimized and the speciation methods of AFS were presented. Results indicated that the methods were accurate and reliable. The recovery and variable coefficient ranged between 82.0%-110.0%, 1.35-2.22%, repectively.
