Description
Summary:Inductively coupled plasma mass spectrometry with the use of a reaction cell in collision mode has been used to determine the concentrations of 68 elemental impurities in six commercially available molybdenum( VI) oxide reagents. The results indicate that the purity of the reagents is not better than 3N (99.9 wt %). A major impurity in the MoO 3 samples is tungsten. Its concentration ranges from 5 × 10 –3 to 6 × 10 –2 wt %, depending on the manufacturer.
