Abstract
An agent for the elution of thiourea-noble metal complexes from active charcoal based on an acidic aqueous solution containing thiourea and an organic solvent, which has a content of 0.1 to 50 g./litre of thiourea and contains at least one organic solvent which is partly soluble in water. Noble metals e.g. gold and silver are by precipitation there of from the aqueous organic phase by the addition of base metals in the presence of a small amount of sulphite and optional reactivation of the active charcoal with an aqueous solution of a sulphite.
