A process for treating acid mine drainage removes iron ions from the acid mine drainage in the form of zero-valent iron nanoparticles which can be subsequently used for environmental remediation.

Process for producing zero-valent iron nanoparticles and treating acid mine drainage

Aqueous acid mine drainage is aerated and treated with slaked lime to reduce ferrous iron as a sludge. Further treatment with an alkaline sodium borohydride solution reduces residual iron and manganese which precipitates out and is removed.

Process for treating mine drainage

A flooding fluid for use in petroleum recovery from a petroleum-bearing formation is prepared by mixing an oxygen scavenger consisting essentially of an alkaline aqueous solution of at least one water-soluble borohydride with an aqueous or nonaqueous input fluid having oxygen dissolved therein to reduce the level of dissolved oxygen.

Method and compositions for enhanced oil recovery

A process for enhanced oil recovery includes the steps of providing an alkali metal borohydride; providing an alkali metal bisulfite; combining the alkali metal borohydride and the alkali metal bisulfite along with water to provide an oxygen-scavenger composition; combining the oxygen-scavenger composition and an aqueous composition to provide an oil recovery solution; and introducing the oil recovery solution into an earthen formation at a pressure to provide for enhanced oil recovery.

Method and composition for oil enhanced recovery

An aqueous fuel for generating hydrogen includes alkaline aqueous composition of about 17 to 37 mole percent of a sodium borohydride, and from about 0.001 to 1 mole percent of sodium hydroxide.
