Abstract
A method for AES-ISP determination of Ti, V, Cr, Fe, Co, Ni, Cu, Zn, and Ta in recycled cemented tungsten carbide is developed including preliminary microwave sample decomposition in a steam pressure vessel (autoclave). We have specified composition of the reaction mixture for sample dissolution and optimized the parameters of microwave heating in the autoclave. Correctness of the results is proved by the method of sample weight variation and spike tests. The results of analysis are compared with the data obtained by standardless method of x-ray fluorescence spectrometry. The technique is characterized by good reproducibility and allows significant reduction of the analysis time due to combination of the multi-element method of AES-ISP and microwave sample preparation.
