| 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 #g/ml titanium(IV) at 580 nm. The
apparent molar absorptivity at 580 nm is 9.82.103 1.mole-l.cm -~ 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. |
