  • Process for separating at least one platinoid element from an acidic aqueous solution comprising, besides this platinoid element, one or more other chemical elements
    Patent number: 9102994
    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.

  • PROCESS FOR SEPARATING AT LEAST ONE PLATINOID ELEMENT FROM AN ACIDIC AQUEOUS SOLUTION COMPRISING, BESIDES THIS PLATINOID ELEMENT, ONE OR MORE OTHER CHEMICAL ELEMENTS
    Publication number: 20130319178
    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 said platinoid element, said process comprising the following steps: a step of bringing said 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, by means of which said platinoid element is reduced to its 0 oxidation state; a step of separating said thus reduced platinoid element from said acidic aqueous solution.
