【摘要】 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^-10g、7×10^-9g和2×10^-9g;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。更多还原

【Abstract】 A chloride generation-atomic absorption spectrometry is described and cadmium, lead and nickel were determined by this method with a new homemade apparatus. The method is of high sensitivity. The apparatus demands no facility for background deduction and near 40 elements can be determined potentially. The sensitivities（1% absorption）of cadmium, lead and nickel are 7×10^-10g, 7×10^-9g and 2×10^-9g and the relative standard deviations are 6.0%, 7.6% and 8.0% respectively.更多还原
