Multi-Element Trace Analysis in Molybdenum Matrix by Inductively Coupled Plasma Atomic Emission Spectrometry
Zun Ung Bae, Sung Ho Lee, Sang Hak Lee
A method for the direct determination of trace amounts in molybdenum matrix by inductively coupled plasma atomic emission spectroscopy is described with emphasis on line selection and spectral interferences. Metal samples were decomposed by microwave-assisted sample digestion method. The spectral interference coefficients were calculated for the 270 spectral lines of 67 elements and these values were used for line selection and to calibrate concentrations of the analytes. The limits of detection of the elements for this method were determined and compared with those obtained by flame atomic absorption spectrometry and direct current carbon arc emission spectroscopy. Analytical reliability of the proposed method was estimated by analyzing a spiked solution and the results indicated that the accuracy of multi-element analysis is satisfactory.
