ABSTRACT
The extraction of Ti(IV) from nitric acid has been carried out using some organophosphorus extractants in kerosene. The Ti(IV) extraction in the investigated systems is endothermic. Oxalic acid was effective for stripping Ti(IV). The maximum loading of Ti(IV) was found to be 6.13 × 10−3, 6.175 × 10−3 and 5.005 × 10−3 M of Ti(IV) per mole extractant for CYANEX 925, 923 and 921, respectively, after five extraction stages. Kerosene is a more effective diluent for extraction of Ti(IV). FT-IR characterization and the separation of Ti(IV) are also discussed.
