摘    要:本文研究了氢化物-无色散原子荧光法同时测定钢铁中痕量硒和碲。采用离子交换法消除了阳离子干扰。在40%(V/V)盐酸介质测定硒和碲,方法检出限分别为0.27和0.33ng/mL,相对标准偏差分别为6.99和6.11%,回收率在96.7 ̄102.0%之间。

关 键 词:氢化物  原子荧光法      离子交换  测定  钢铁

Abstract:A method was developed for the determination of trace Se and Te in steel by ion-exchange-separation hydride-generation nondispersive atomic fluorescence spectrometry. 40% (V/V) chlorhydric acid was selected as the best medium for hydride reaction. The detection limits of Se and Te are 0.27 and 0.33 ng/mL, relative standard deviations are 6.99 and 6.11%, respectively. The recovery was in the range of 96.7-102.0%. The results are satisfactory.
Keywords:Hydride    Atomic fluorescence spectrometry    Selenium    Tellurium    Ion exchange
