URINALYSIS FOR CURIUM BY ELECTRODEPOSITION
A urinalysis method was developed for the determination of curium by electrodeposition. The urine is wet ashed, and the curium coprecipitated with bismuth phosphate, then lanthanum fluoride, and finally lanthanum hydroxide. The curium is separated from the lanthanum carrier using Dowex-50 colloidal ion exchange resin. Electrodeposition on a stainless-steel or platinum disc gives a uniform film suitable for pulse-height analysis or low-background proportional counting. Final analysis of weak samples is done by radioautography. Curium recoveries of approximately 45% are obtained. Quantities of the order of O.2 dpm can be detected by this method. (auth)
