Abstract
Tributylphosphine oxide is proposed as an extractant for uranium(VI) a nd thorium(IV) from salicylate media. The optimum extraction condition s were evaluated by studying various parameters such as pH, sodium sal icylate concentration, tributylphosphine oxide concentration, diluents and shaking time. The extracted species were ascertained by logD-logC plots. The method is simple, fast, precise and permits the separation of uranium(VI) and thorium(IV) in binary as well as multicomponent sy stems. The method is also applied for the determination of uranium(VI) and thorium(IV) in monazite sand samples.
