Determination of Niobium and Tantalum in Geological Materials by Atomic Emission Spectroscopy with Inductively Coupled Plasma

Abstract

A method using atomic emission spectroscopy wjth inductively coupled plasma has been de­ veloped for determination of low Nb and Та contents in geological materials. The sample decom­ position and the stabilization of Nb and Та in the gained solution, as well as the separationpreconcentration procedure are described. The study of interferences, among which the Fe influ­ ence is the most significant, is performed and appropriate correction proposed. The reliability of the described procedure is checked by the analysis of certified reference materials and in the case of Та also by instrumental neutron activation analysis.
