Determination of palladium in sulfide-bearing rocks by electrothermal atomization atomic absorption spectrometry with a continuous spectrum source

Abstract

A possibility of the direct determination of palladium in dissolved samples of platinum sulfide ores by high-resolution electrothermal atomic absorption spectrometry with a continuous light source without preconcentration and separation from the matrix components is investigated. The conditions of analysis are selected and a procedure for the determination of palladium is developed. The results of determination well agree with the data obtained using extraction separation and traditional atomic absorption spectrometry with selective line spectrum sources. The accuracy of the results was estimated by the added–found method.
