Title:

How to separate at least one sort of platinoid elements from the aqueous acids which contain one or more sorts of other elements in addition to a platinoid element

Document Type and Number:

Japanese Patent JP5957013

Kind Code:

B2

Abstract:

The invention relates to a process for recovering at least one platinoid element contained in an acidic aqueous solution comprising chemical elements other than the platinoid element, the process comprising the steps of (a) bringing the acidic aqueous solution into contact with a reducing amount of a reducing agent which is a non-sulphurous and non-glucidic alcoholic compound chosen from cyclic, optionally aromatic, alcohols and aliphatic polyols, which reduces the platinoid element to its 0 oxidation state; and (b) separating the reduced platinoid element from the acidic aqueous solution.
