Abstract
The present invention is drawn to a method for removing colloidal titanium dioxide and titanium oxychloride from by-product hydrochloric acid. The method includes adding phosphate ion source and quaternary amine to the by-product acid to cause the titanium dioxide and the titanium oxychloride to form a precipitate. The precipitate can then be separated from the acid, thus producing a decontaminated hydrochloric acid product with reduced levels of titanium.
