  • Alkali metal borohydride/anionic polymer solutions
    Patent number: 5354478
    Abstract: An aqueous solution of sodium borohydride, sodium hydroxide, and an anionic polymer is useful for the reduction and separation of metals in wastewater and it is hydrolytically stable for a period of six months. It may also contain an alkali metal aluminate or alum. Thus, a one-package treatment of wastewater is provided by the invention described herein.

  • Method for prevention of metallic precipitate reoxidation/redissolution in aqueous systems
    Patent number: 4698162
    Abstract: 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.
