Analytical Study of Enrichment of Low Content Platinum in Natural Minerals by using Polymeric Sorbent

Samgain Odonchimeg, Jamba Oyun, Namsrai Javkhlantugs


In order to enrich low content platinum (Pt), polystyrene-azo-thiazan-dithion-2.4(PSTDT) has been selected from several polymeric sorbents that able to create with it a chelate complex. We studied physical-chemical characteristics of sorbent and their complexes with platinum. Analytical parameters of condition for platinum concentration are determined. The platinum sorption process with sorbents having thiazan-dithion groups runs with detaching of two protons from FAG. In the complex these results allow to suggest the obvious, structure of chelate fragments. We define that in the optimal conditions for platinumsorption [H+], sorption all time and temperature. A new rapid and reliable method of concentration and derivation of quantitative of (Pt) natural minerals objects by polymeric FAG thiazan-dithion groups is proposed.
