Direct spectrophotometric determination of titanium(IV) with 5-bromo-2- hydroxy-3-methoxybenzaldehyde-p-hydroxybenzoic hydrazone


5-Bromo-2-hydroxy-3-methoxybenzaldehyde-p-hydroxybenzoichydrazone reacts with Ti(IV) forming thick orange coloured soluble complex in aqueous dimethyl formamide in the pH range 2.0-7.0. It has a λmax at 390 nm. Studies were carriedout at pH-4.0.The method obeys Beer’s law in the range 0.241 to 2.87 μg /ml. The molar absorptivity is 1.44×104 l mol-1cm-1 and Sandell’s sensitivity is 0.0033 μg/cm2. The standard deviation of the method for ten determinations of 1.197 μg/m l o f T i ( IV) i s 9.04×10-3. T h e correlation coefficient (γ) of the calibration equation of the experimental data is 0.9998. The effect of various diverse ions is studied. The formula of the complex is 1:1 and its stability constant is 2.25×105. Based on the above , a rapid, simple, sensitive and selective direct spectrophotometric method has been developed. The method developed was used for the determination of Ti(IV) in alloy and steel samples. The results are in good agreement with the certified values.
