Abstract The reaction between titanium(IV) and 2-(2-thiazolylazo)-p-cresol-(TAC) in aqueous methanol media at apparent pH 4.0–5.6 results in a intensely coloured complex that is stable for at least 2 h. The combining ratio is 1 ∶ 1 cation ∶ TAC. Beer's law is obeyed up to 5.0 μg/ml titanium(IV) at 580 nm. The apparent molar absorptivity at 580 nm is 9.82.103 l.mole−1.cm−1 and the detection limit obtained was 5 ng/ml titanium (IV). A spectrophotometric method for the simultaneous determination of titanium and iron with TAC is proposed.
