Název v původním jazyce
Ac-225/Bi-213 Generator System Based on α-zirconium Phosphate Ion Exchanger
Popis výsledku v původním jazyce
The capacity study of prepared α-zirconium phosphate monohydrate (α-ZrP) ion exchanger granulated in polyacrylonitrile matrix (70% loading) was carried out with Eu as a homologue of Ac-225 using column model of future high activity generator and a stock solution Eu with Eu-152 of activity 57.2 kBq. The fractions of Eu-152 solution were collected after pumping the stock solution through the column at various times for gamma measurements and further calculations of theoretical sorbent capacity for Ac-225 which was evaluated as 36.7 TBq/g. The model high activity (75 MBq of parent Ac-225) generator with length of bed of 7.5 cm and diameter of 0.4 cm containing α-ZrP (particle size 0.8-1.0 mm) as a stationary phase eluted with mixture of 0.01M diethylenetriaminepentaacetic acid (DTPA) in 0.005M nitric acid provided Bi213 with yields in the range from 80 to 95 % in 2.6 ml of eluate and the contamination by parent Ac-225 was in tens of ppm up to forty days of using with flow rate of 0.33 ml/min.
