加入1 × 10− 2 M铈（IV），可使火焰原子吸收光谱法测定钌的灵敏度提高60倍。在0.05-5 μg ml− 1钌范围内，校准呈线性。描述了一种适用于亚硝酰基钌络合物的方法。增加的灵敏度是由于四氧化钌的形成。
The sensitivity of the determination of ruthenium by flame atomic absorption spectrometry is increased 60 times by adding 1 × 10−2M cerium(IV). Calibration is linear over the range of 0.05–5 μg ml−1ruthenium. A method applicable to nitrosylruthenium complexes is described. The increased sensitivity results from formation of ruthenium tetroxide.
