A spectrophotometric method for the determination of traces of aluminium in titanium oxide has been described. The method was based on selective extraction of titanium as TiCl4.2TBP (TBP = tri-n-butyl phosphate) with TBP in CCI4 in 11N HCI medium. Aluminium was then determined at pH 5.3 with xylenol orange in presence of tartàric acid in aqueous medium by measuring the extinction at 530 nm. The deleterious effect of traces of titanium left unextracted in the aqueous medium has been taken care of and removed by masking with H2O2. The method obeyed Beer's Law up to 2 μg Al2O3/ml and yielded satisfactory results in its application to different titania samples.
