TITANIA-BASED TREATMENT SOLUTION AND METHOD OF PROMOTING PRECIPITATION AND REMOVAL OF HEAVY METALS FROM AN AQUEOUS SOURCE

摘要

A treatment solution and method for removing heavy metal contaminants and oxyanion contaminants from an aqueous solution by promoting the affinity of precipitating the contaminants. The method adjusts the pH and the ORP of the contaminated aqueous solution by applying FeCl₂ and/or NaOH reducing agents, and using and applying a titania-based treatment solution of TiO(SO₄), H₂SO₄, and FeSO₄.
