Abstract
The capabilities of inductively coupled plasma atomic emission spectrometry (ICP-AES) for the determination of tantalum in alloy steels without separation of matrix components have been analyzed. The analytical lines of tantalum and the method of sample preparation are selected. The effect of acids present in the analyzed solution on the analytical signal of Та has been studied. Optimal conditions of measurements were determined by changing one of the operational plasma parameters at simultaneous stabilization of all other parameters. The influence of the components of alloy steels on the analytical signal of tantalum has been studied. The metrological characteristics of the technique were evaluated proceeding from the results of analysis of certified mixtures (CM). To assess the correctness of the results obtained we used certified mixtures and standard addition technique. A method for measuring the mass fraction of tantalum in alloy steel samples by ICP-AES in the content range from 0. 01 % to 0. 05 % has been thus developed.
