本文研究了用常压微波诱导等离子体作为原子吸收光谱法的原子化器的可行性, 采用电热蒸发浓硫酸去溶微量进行装置进样, 详细考察了各种实验参数对测定铜的影响。实验证明测定Cu、Ag、Pb的特征浓度分别为0.04、0.04、0.1μg/ml。

An atomsphere pressure MIP is used as an atomizer for atomic absorption spectrometry. The sample solution was introduced with an electrothermal microsample introduction system combined with concentrated H2SO4 desolvation. The experimental parameters affecting the determination of copper were examined in detail. The characteristic concns. for Cu, Ag, and Pb were shown to be 0.04, 0.01, and 0.1 mg/mL, resp.
