Abstract
Evolution of the mother liquor pH in the course of the sol-gel precipitation of hydrogels of yttrium and europium oxohydroxides has been studied at different acidity of the system and the precipitant (NaOH) concentration. The optimal pH and components concentrations have been determined; the specific surface area of 210 m2/g (yttrium hydroxide) and of 100 m2/g (europium hydroxide) has been attained under these conditions.
