电感耦合等离子体原子发射光谱法直接测定锑及三氧化二锑中砷量

Determination of Arsenic by ICP-AES in the Antimony and Antimony Trioxide

提出和建立了电感耦合等离子体原子发射光谱法直接测定锑及三氧化二锑中砷量的方法。选择波长为228.812 nm的谱线作为测定砷的分析线,方法的检出限0.081μg/mL,检测结果的相对标准偏差小于6.5%,回收率为94.5%~103.5%。

Proposed and established the method of detect measurement in arsenic by the inductively coupled plasma atomic emission spectrometry of antimony and antimony trioxide. The spectral line of 228. 812 nm was selected as analytical line for the determination,the limit of detection is at 0. 081 μg /mL,RSD of the measurement is less than6. 5% and the recovery rate is in range of 94. 5% ~ 103. 5%.
