  • Abstract

    3,4–Dihydroxybenzaldehydeisonicotinoylhydrazone(3,4-DHBINH) was prepared, characterized with spectral analyses and used for developing a new method for the simple, sensitive and rapid spectrophotometric determination of titanium(IV) which gives maximum absorbance at wave length 370 nm. The metal ion gives a yellow colored complex with 3,4–DHBINH in acetate buffer of pH 3.5 with 1:2 (metal: ligand) composition. The method obeys Beer’s law in the range 0.5–4.25 ppm of titanium(IV). The molar absorptivity and Sandell’s sensitivity were found to be 1.489x104 L mol-1 cm-1 and 0.003217 µg cm-2, respectively at 370 nm. The correlation co-efficient of the Ti(IV)-3,4-DHBINH complex was 1.00125 which indicated an excellent linearity between the two variables. The repeatability of the method was checked by finding the relative standard deviation (RSD) as 0.347% (n=5) and its detection limit
    0.0053 µg mL-1 of titanium(IV). The interfering effect of various cations and anions were also studied.
