4DescriptionAbstract An extractive spectrophotometric method is developed for the trace determination of titanium with 6-chloro-3-hydroxy-2-(2-furyl)-4-oxo-4H-1-benzopyran (CHFB) in presence of sodium sulphite in acidic medium which was extracted into dichloromethane and shows maximum absorbance at 432 nm. Beers law is obeyed in the range 0.0 to 2.5 μg of Ti mL-1 having molar absorptivity, specific absorptivity and Sandells sensitivity value of 1.659?104 Lmol-1cm-1, 0.346 mLg-1cm-1 and 0.00289 μg of Ti(IV) cm2 respectively at 432 nm. The limit of detection of the method is 0.017 ppm. The method is free from the interferences of a large number of cations of major analytical importance such as Pr(III), Ba(II), Mn(II), V(V), Ca(II), La(III), Cr(VI), Se(IV), Bi(III), Re(VII), Ce(IV), Sb(III), W(VI), Tl(I), Cd(II), Rh(III), Be(II), Sr(II) and platinum metals. Nitrate, chloride, sulphate, acetate, iodide, bromide and thiourea do not interfere. The applicability of the method was tested by analyzing satisfactorily a wide variety of samples with good reproducibility
