砷分族元素,尤其是砷、锑具有易挥发、难激发的特性,经典发射光谱法测定灵敏度低,近年来有用氢化反应-原子吸收测定砷分族,锗分族及硒碲的报告,该法灵敏度高,但只能作单元素测定。ICP-AES氢化法改善了经典发射光谱及原子吸收法之不足,是高灵敏度同时测定上述元素的有效方法。本文用国产仪器研究了ICP-AES连续氢化法测定砷分族元素时,影响谱线强度的诸因
Arsenic, especially arsenic and antimony, have the characteristics of easy volatility and hard-to-fire excitation. The emission spectra of classical arsenic and antimony have low sensitivity. In recent years, there are reports of arsenic, germanium and selenium tellurium by hydrogenation-atomic absorption spectrometry Sensitivity method, but only for single element determination. ICP-AES hydrogenation method to improve the classical emission spectroscopy and atomic absorption method of the deficiencies, is an effective method for simultaneous determination of the above elements with high sensitivity. In this paper, with the domestic equipment ICP-AES continuous hydrogenation method for the determination of arsenic when the elements of the line, the impact of spectral line
