The reaction between Ti (IV) and 3, 4-Dihydroxybenzaldehyde isonicotinoyl hydrazone (3, 4-DHBINH) has been investigated in sodium acetate and acetic acid buffers. A highly sensitive and simple procedure for the determination of Ti (IV)is suggested. The orange coloured complex shows maximum absorption at 420 nm in a buffer solution of pH6.0. Thecompositionofthecomplexis1:1(M: L). Beers law is obeyed in the range 0.478µg/ml to 2.394µg/ml. The molar absorptivity and Sandell’s sensitivity are calculated as 1.4933 x 104 L mol-1 cm-10.00317µg/cm-2respectively.
Keywords: 3,4-Dihydroxy benzaldehyde isonicotinoylhydrazone, titanium(IV), spectrophotometry.
