Аннотация
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 μL 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 (R2) 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 98‒99%.
