Spectrophotometric method has been developed for the determination of titanium(III). The linear calibration curve was obtained with 2-10 g/ml titanium. The titanium was determined in pharmaceutical preparation with coefficient of variation 3.0%. The concentration of titanium was calculated from the standard calibration curve and was found 111.25 µg/ml with coefficient of variation 3.0%. The obtained results agreed with the results obtained from hydrogen peroxide (H2O2) method.
