Abstract
Spectrophotometric studies of titanium(TV)-Morin complex in the presen ce of an anionic surfactant shows that the ligand forms a 1:3 complex with a formation constant of 2.72 x 10(16), which is ten times greater than that obtained in the absence of a surfactant. The effect of diff erent variables such as pH, temperature, surfactant concentration, sta nding time and diverse ions was studied. The calibration graph was lin ear in the range 0.04-1.4 mu g/mL of Ti(TV) and the detection limit wa s 0.007 mu g/mL. The method was applied to the determination of titani um(IV) in mineral samples.
