摘要：

Trace amounts of titanium(IV) were determined with a simple and selective method based on cloud point extraction. Preconcentration of titanium from aqueous solution was performed using Triton X-114 surfactant and 4-(2-pyridylazo) resorcinol as complexing agent. After centrifugation, the surfactant- rich phase was removed, diluted with water and ethanol, transferred into a 500 mu L quartz cell, and its absorbance was measured at 520 nm. The effect of experimental conditions influencing the extraction process was considered. In the optimum conditions, linearity ranges was 0.01-0.1 with the correlation coefficients (R-2) of 0.9903. The limits of detection was 0.005. The method was successfully used for the determination of titanium(IV) in the samples of ore and river water with relative recovery of 98aEuro'99%.
