摘要：

The sorption activity in solutions of chioroplatinic acid composites based on copolymers of ethylene glycol vinyl glycidyl ether (VGE) and vinyl chloride (VC), NN- bis(3-triethoxysilylpropyl)thiourea (BTM-3) and 2-(ftriethoxysilylpropyl]amino)pyridine (TEAP) was studied. Contemplated hybrid composites containing thiourea groups (sorbent on based BTM-3) and pyridine fragments (sorbent on based TEAP), which causes their high sorption activity with respect to chlorine anion of platinum. It is shown that increasing the concentration of hydrochloric acid reduces the activity of composites sorption by enhancing acido-complexes Pt (IV) stability in solution. Absorption characteristics of the synthesized materials relative to the platinum (IV) ions are defined; sorption capacity values and metal interphase distribution coefficients at various temperatures are calculated. BTM 3 based composite exhibits a high sorption activity.
