SORPTION-SPECTROPHOTOMETRIC DETERMINATION OF Al (III), Ga (III), In (III) ВY USING DIMETHYLCHLOROSILANEAEROSILE, IMPREGNATING BY POLARITY SOLVENT

Abstract

The sorption-spectrophotometric determination techniques (metodic) of Al (III), Ga (III), In (III) microquantities has been developed, including previouslyseparation of elements-analogs with the use of dimethylchlorosilaneaerosile (DMCSA), impregnated by polar organic solvent – ethanol or acetone depending on pH. The conditions of Ga and In quantitative desorption from DMCSAsurface by using ultrasonic radiationwere optimized. Spectrophotometric determination of Al, Ga, In, located in separate portions of the solution,was carried out with xylenol orange by known methods. The methodicwas tested on circulating waters of alumina production.
