A new spectrophotometric method for the determination of trace amounts of titanium(IV)

A new, rapid, simple, precise and extraction-free spectrophotometric method is proposed for the micro determination of titanium(IV) employing N'-(2-hydroxybenzylidene)- 3-oxobutanehydrazide as a reagent. Under the optimum conditions established, the absorbance was found to increase linearly with the concentration of titanium(IV) in the range 1.757 to 17.57 μg mL 1. The method parameters such as the molar absorptivity, Sandel sensitivity, stoichiometry of the complex, method detection limit and limit of quantification were reported. The reproducibility of the method was excellent and recoveries reported were ranging from 102 to 104%. The proposed method can be readily applied for the determination of titanium(IV) in synthetic mixtures and alloys.
