摘要：

Triphenylarsine oxide is proposed as an extractant for the solvent extraction of uranium and thorium salicylates. ?he optimum extraction conditions an: established by studying the various parameters such as pH, sodium salicylate concentration, triphenylarsine oxide concentration, diluents and shaking time. The probable extracted species as ascertained by log D-log C plots are UO2(Hsal)(2) . 2TPAsO and Th(Hsal)(4) . 2TPAsO. The method is simple, fast, precise and permits the determination of uranium and thorium in monazite sand samples.
