Determination of Europium and Gadolinium in Single Crystals of Europium-Doped Potassium Gadolinium Tungstate by Means of Electrothermal Atomic Absorption Spectrometry and Titrimetry

Autor: Gentscheva, Galja, Ivanova, Elissaveta, Havezov, Ivan

A rapid combined method is developed for the analytical control of the content of europium and gadolinium in single crystals of europium-doped potassium gadolinium tungstate. The crystal material is dissolved using hydrofluoric acid, and hydrogen per
