Rakhlytskaya Е. The surface hydrolysis on the concentration and separation of Al(III), Ga(III), In(III) by hydrated and alkylated silica

This work describes a study of physical and chemical mass transfer regularities of ion-molecule forms Al(III), Ga(III), In(III) and associated elements (Sb(III), Bi(III), Ti(IV), Fe(III), Cr(III), Zn(II), Co(II), Pb(II), Ni(II)) in a heterogeneous systems "hydrated dioxide - adsorbate aqueous solution" and "dimethylchlorosilaneaerosile (DMCSA) - polar solvent (S) - ad-sorbate aqueous solution" for the further development of combined assay methods for sorption-spectrophotometric determination of the subgroup of aluminum elements microquantities, by combining their preliminary separation using this system and the subsequent separate determination with xylenol orange (XO) using variants of absorption spectroscopy (SPS), diffuse reflectance spectroscopy (DLS) and visual colorimetric (VC) test determination.
