TERPENE BASED AMINO OXIMES ON SOLID SUPPORTS AS SELECTIVE EXTRACTANTS OF PRECIOUS METALS

Chelators based on terpene bis(α-amine oximes) applied onto low-polar sorbents (coal, Sibunit, Polysorb) are effective selective extractants for the extraction of palladium and gold from acidic aqueous solutions containing the mixtures of precious metals and 3d-elements. The use of sorbents impregnated with the new chelators allows extraction in the liquid-solid mode without using any organic solvent.
