| Summary: | Sorption-colorimetric and naked eye determination of germanium as ion associates of GeMo O 4– with triphenylmethane dyes is described. The sorption of the ionic associates (IA) of 12molybdogermanat with astrafloxin (AF) on filter paper was studied. The colored scales for naked eye detection and dependence of chromaticity coordinates from the germanium (IV) concentration were obtained. The methods were applied to the determination of germanium (IV) in coked coal, iron ore, and in waters in the concentration range from 4•10–8 to 1•10–6 mol•L–1. The developed test-systems for the determination of Germanium in natural and technological objects were tested in the course of training students of chemistry of Kryvyi Rih State Pedagogical University. |
