Получение катионообменного сорбента для хроматографической колонки генератора 99mTc

A new cation exchange sorbent based on polyethylene powder modified by polyacrylic acid was prepared for technetium-99m generator column. The dependence of the kinetics of polyethylene modification on the structure of grafting solution was studied. The adsorption of manganese ions by the obtained sorbent has been studied. The new sorbent was tested in technetium-99m generator column with the maximum output activity. It is expedient to use the sorbent in a technetium-99m generator column in order to improve the quality of effluent, increase the stability of the yield of pertechnetate ions, and maintain the eluate medium in a condition close to neutral.
