Abstract:
In at least one embodiment, a method for remediating oxic water having transition metal ions comprises the steps of providing oxic water having transition metal ions. The water is introduced to a chamber. The pH is adjusted to a range from 2.5 to 7.5 forming a pH-adjusted oxic water. Thiosulfate ions are introduced and reacted with the transition metal ions to form insoluble transition metal-thiosulfate species complexes, which are immobilized forming remediated oxic water.
