A method of treatment of an aqueous Phase comprising acid, sulphate ions, especially sulfuric acid, Titanium ions, particularly TITANIUM (iv), and metal ions, particularly Iron (ii).

摘要

Method for the Recovery of Titanium ions and sulfuric acid from an aqueous Phase comprising Titanium ions and sulfate ions, Iron ions.It includes the following Operations: First, is in contact with the aqueous Phase with an organic Phase containing at least one extracting Agent selected from the group of products of formula (i), in which a and B are groups R1 or R2, being a and B EQUAL 8th R1 and R2 are different, and Radic Alcohilo ales, alquenilo, alquinilo,Aryl or alcohilarilo; and R is a radical of the same type as those defined for R1 and R2; Second, recovers an aqueous Phase comprising all final Fe (ii) ions present in the initial aqueous Phase; and, finally, recovers an organic Phase comprising the entire final sulfuric acid and tod Os Titanium ions present in the aqueous phase.
