Abstract

To ensure analytical support for the growth of bismuth orthogermanate single crystals, we have developed an electrothermal atomic absorption technique for analysis of germanium dioxide with the separation of the host through reactive evaporation in the form of germanium tetrachloride. The technique allows Cd, Co, Cu, Cr, Mn, Ni, and Pb to be determined with detection limits in the range 1 × 10−8 to 1 × 10−8 wt %.
