Abstract

This article considers the study of sorption of palladium (II), platinum (II), and platinum (IV), from the hydrochloric-acid solutions by chemically modified silica. Using the methods of infra-red and electronic spectroscopy, there were established such types of complexes, which are obtained in the phase of sorbent (silica, which is modified by the groups of γ- aminopropyltriethoxysilane), depending on the solution acidity. The hydrochloric-acid solutions of thiourea were proposed as the eluent. A sorption separation diagram for Pd (II) and Pt (IV) was proposed on the basis of the study.
