Abstract
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 FeCland/or NaOH reducing agents, and using and applying a titania-based treatment solution of TiO(SO), HSO, and FeSO.
