ICP-AES DETERMINATION OF SOME METALLIC IM PURITIES AND DOPING AGENTS IN HIGH-PURITY ORGANIC ZINC-COMPOUNDS

This paper presents the determination by inductive coupled plasma - at omic emmision spectrometry method (ICP-AES) of some disturbing impurit ies (i.e. Al, Ca, Cd, Co, Cu, Cr, Fe, Mg, Mb, Ni, Pb) in the zinc or z inc-based luminophores used for getting varistors,as well as in the mo st frequently used doping agents (i.e. Ag, Bi, Co, Cr, Cu, Mo, Sf) in the field.
