Plutonium nitrate solution stored for long after separation from uranium and fission products by anion-exchange and containing a large amount of hydroxyl-amine hydrochloride used as eluent, was repurified by anion-exchange. Radiochemical determination of plutonium isotopes-both in the purified plutonium solution and waste solution - was also studied.
The results were as follows;
(1) Pu(IV) was adsorbed on anion-exchange resin (Dowex-1×2, 200-400 mesh) in 7.2N nitric acid solution at about 60°C, and was eluted with 0.35 N nitric acid.
(2) Plutonium was recovered with a yield of 97%.
(3) High purity plutonium was obtained, leaving 241Am in the waste solution.
