本文应用氯化物发生原子吸收光谱法这一新技术,在自行设计的装置上分别对镉、铅和镍进行了考察;选出了合适的操作参数。它们的测定灵敏度(1％吸收)分别为7×10~(-10)g、7×10~(-9)g和2×10~(-9)g;10次测定的相对标准偏差分别为6.0％、7.6％和8.0％。该方法装置简单,测定灵敏度较高,预计可测近40种元素。 In this paper, the new technology of chloride atomic absorption spectrometry was used to investigate the cadmium, lead and nickel respectively on the self-designed devices; and the suitable operating parameters were selected. Their sensitivity (1% absorption) were 7 × 10 ~ (-10) g, 7 × 10 ~ (-9) g and 2 × 10 ~ (-9) g, respectively. The relative standard deviations 6.0%, 7.6% and 8.0%. The method has the advantages of simple device and high determination sensitivity, and nearly 40 elements are expected to be measured.
