Abstract:
1. A method for remediating oxic water having transition metal ions, the method comprising the steps of: (a) providing oxic water having transition metal ions; (b) introducing the oxic water to a chamber defining a cavity; (c) adjusting a pH of the oxic water to a pH ranging from 2.5 to 7.5 forming a pH-adjusted oxic water; (d) introducing thiosulfate ions to the pH-adjusted oxic water; (e) reacting the thiosulfate ions with the transition metal ions to form insoluble transition metal-thiosulfate species complexes; (f) immobilizing the insoluble transition metal-thiosulfate species complexes forming remediated oxic water; and (g) releasing the remediated oxic water.
