Abstract: The possibility of separating beryllium from Ni, Cu, AI, Fe, Ti and V on the column with the help of the CO₃^2- form of AV-17 anion exchanger (the column of 1.6 cm in diameter, layer thickness of sorbent 15 cm) has been ascertained during the following scheme of elution: the desorption of Ni, Cu, Al — 400 ml 3 N - NH₄OH solution; the desorption of Be — 20 ml 1 N-NaOH solution; the desorption of Ti and V — 1150 ml 3 N-NaOH solution; the desorption of Fe — 200 ml 1.5 N-HCl solution. The maximum relative error of determination of beryllium (after its separation from elements which hinder determination) by the photocolorimetric method does not exceed ± 8.0%.
