Description

Here is reported the separation of uranium (VI) in phosphoric acid by liquid-solid extraction with TAPO(Tri-Alkyl-Phosphine Oxide) and wax. The organic phase is stripped with 0.12 mol/l NaF solution. The uranium is determined spectrophotometrically with Arsenazo III and the fluoride ion is masked with 4% boric acid. Results of analysis of phosphoric acid samples by this method are given
