Abstract : The chemical analysis of titanium is complicated by the tendency of its ions to hydrolyze in neutral or slightly acidic solutions. However, in 0.3M oxalic acid, the titanium solutions remain stable and clear because hydrolysis of titanium is prevented. Therefore, sample solutions of various inorganic ions were prepared in oxalic acid to determine titanium. Aliquots of the sample solutions can be taken for the spectrophotometric determination of 0.004% to 10.0% titanium with tiron. The exclusion of fluoride reagents eliminates a source of color interference and a health hazard. (Author)
