ABSTRACT:
A method for manufacturing titanium oxide, comprising bringing a sulfuric acid solution containing predominantly titanium ion together with one or more kinds of metal ions into contact with an organic solvent containing one or more species selected from the group of oxygen-containing organic solvents, alkyl amines, and alkyl aryl amines to extract the titanium ions in a form of a sulfuric acid complex from the sulfuric acid solution, and bringing the organic solvent containing the extracted titanium into contact with water or an aqueous dilute sulfuric acid solution to inversely extract the titanium from the organic solvent to the water or the dilute sulfuric acid solution and to regenerate the organic solvent.
