<p>Redissolution and/or reoxidation of metals precipitated by chemical reduction from aqueous solutions can be prevented by adding a bicyclic, aromatic, organonitrogen compound to the solution in a amount insufficient to cause precipitation of said metal but sufficient to prevent the redissolution and reoxidation of the precipitate. The compounds added can be selected from benzotriazoles, benzothiazols and benzimidazoles.</p> |
