Abstract
A method for accurate and precise determination of trace molybdenum in drinking water by isotope dilution inductively coupled plasma mass spectrometry was developed, given the concentrations of Mo in drinking-water samples from Chaoyang and Changping districts of Beijing (China) as 1.017 ± 0.008 and 1.033 ± 0.007 μg kg−1 (k = 2), respectively. Special care was taken for the validation of the proposed ID-ICPMS method using CRM 7203-a, a certified reference material for elemental analysis of tap water.
