应用新研制的连续流动氢化物发生器原子吸收测定地质样品中砷、锑、铋

Determination of Arsenic, Antimony and Bismuth in Geological Samples by Atmoic Absorption Spectrometry with a |New Designed Continuous Flow Hydride Generation

本文研制了一种连续流动式氢化物发生器,并用该仪器对As、Sb、Bi、Se、Te、Hg等6元素进行了检出限、精密度等指标的测试,结果均与文献值相当.本文同时报导了用此仪器测定地质样品中As、Sb、Bi的分析方法.对部分标样进行分析的结果,与推荐值相符.

A simple continuous flow hydride generator is designed and Its construction is described in this paper. By using this device, the precisions, detection limits of arsenic, antimony, bismuth, selenium, tellurium, and mercury have been tested, and the obtained results are as good as the literature values. Analytical method for the determination of arsenic, antimony and bismuth in geological samples is also reported in this paper. Some of the standard refereace samples have been analyzed. ,The results obtained are in good agreement with the certified value.
