给出了一种氢化物发生原子吸收光谱法测定工作场所空气中颗粒砷、砷化合物和三氧化二砷蒸汽质量浓度的方法。适用于测定每个样品约100 ng至125 g砷的质量浓度。不适用于测定金属砷化物形式的砷。

Gives a method by hydrid generation for the atomic absorption spectrometric determination of the mass concentration of particulate arsenic, arsenic compounds and arsenic trioxide vapour in workplace air. Applicable to the determination of mass concentrations of approximately 100 ng to 125 g of arsenic per sample. Not suitable for the determination of arsenic in the form of metal arsenides.
