Spectrographic determination of impurities in ammonium hydrogen fluoride samples. II. Study of the behaviour of the added matrices; Determinacion espectrografica de impurezas en bibluoruro amonico. II. Estudio del comportamiento de las matrices adicionadas

Abstract

In order to account for the variations In the shape of the excitation-volatilization' curves and the values of the line intensities of the different impurities determined in ammonium bifluoride, the behaviour of the added matrices (graphite, 63203, GeO{sub 2}, MgO and ZnO) has been considered. With this aim the influence of the added matrices on the are discharge parameters (temperature and electronic concentration) and on the exhaustion rate of the electrode load as a function of the excitation time has been studied. On the other hand, the curve of variation of the line intensity of the metallic component of each matrix versus time has been obtained and the residues in the electrode cavity have been investigated by X-ray powder diffraction.
