ABSTRACT:
The invention herein provides a method for the time delayed precipitation of a solid phase of metal from a low pH, metal salt solution comprising adding to the metal solution a substrate, such as an amide, and an enzyme, such as an amidase, which will react with the substrate, which causes a rise in pH upon the reaction of the substrate with the enzyme. The rise in pH causes the metal to precipitate from solution. The precipitated metal is useful for emplacing metal hydroxides for providing sorptive material useful for removing contamination from groundwater.
