本文给出了在不同炉管和不同平台炉以及采用硝酸镍和抗坏血酸作基体改进剂条件下镓的原子化温度曲线。提出了石墨炉原子吸收法测定镓时原子化机理,探讨了基体增敏作用的机理。
In this paper, the atomization temperature curves of gallium under different furnace tubes and different platform furnaces and the use of nickel nitrate and ascorbic acid as matrix modifiers are presented. The atomization mechanism of gallium when graphite was determined by graphite furnace atomic absorption spectrometry was discussed, and the mechanism of sensitization of matrix was discussed.
