ORGANIC SOLVENTS EFFECT ON THE AL, GA, IN EXTRACTION FROM AQUEOUS SOLUTIONS BY ORGANOSILICAS
Journal Title: Вісник Одеського національного університету. Хімія - Year 2015, Vol 20, Issue 4
Abstract
The adsorption properties of organosilicas – dimethylchlorsilaneaerosil (DMCSA), previously hydrophilized by organic molecules of the polar nature (ethanol, acetone) to wards to aqueous solutions of Al, Ga, In were studied. It is shown that allocation of sorbate in from the aqueous phase in the solvating layer of hydrophilizer and then to surface DMCSA. The selectivity of an organized system “ DMCSA – polar organic solvent” in relation to the elements under study determined by the nature of the impregnated solvent, as well as differences in kinetic and acid-base parameters of the components of heterogeneous system in the process of sorption.
