在过去的报告中,我们曾详细地报导了有关氢化物——无色散原子荧光光谱法的实验技术及有关装置。目前,我们已将这个方法应用于化探样品中测定微量砷、锑及铋。两年来,在我们的实验室中已分析了近三万个样品。方法简便、快速。 关于硒及碲的测定Kirkbright曾作过报导,但是,检出限较差。Nakahara等也曾详细研究了硒及碲的测定,所报导的检出限分别为0.3及30ng,由于采用了碘化碲无极灯,碲的测定受到铋的光谱干扰。在本 In the past reports, we have reported in detail about the experimental techniques and related devices for hydride-free dispersive atomic fluorescence spectrometry. At present, we have applied this method to the determination of trace amounts of arsenic, antimony and bismuth in geochemical samples. In two years, nearly thirty thousand samples have been analyzed in our laboratory. The method is simple and fast. Kirkbright has reported on the determination of selenium and tellurium, however, the detection limit is poor. Nakahara et al. Have also studied the determination of selenium and tellurium in detail. The reported detection limits are 0.3 and 30 ng, respectively. Due to the use of a tellurium iodide electrodeless lamp, the determination of tellurium is influenced by the spectral interference of bismuth. In this
