METHOD AND APPARATUS FOR EXTRACTING AND PROCESSING MOLYBDENUM-99 Russian patent published in 2015 - IPC C01G39/00

Abstract RU 2548033 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of extracting molybdenum. The method includes steps of: feeding a solution of irradiated fuel into an extraction system, wherein the solution of irradiated fuel contains iodine, molybdenum and other fission products, and the extraction system comprises at least one extraction column with a sorbent, passing the solution of irradiated fuel from the bottom upwards through at least one extraction column with a sorbent; feeding the solution of irradiated fuel into a fuel treatment system using at least one outlet cross-over valve; feeding the eluate obtained from the extraction column into an iodine removal system; removing iodine from the eluate obtained from the extraction column; purifying the eluate obtained from the extraction column; and sorbing the purified eluate. A molybdenum extraction apparatus is also disclosed.

EFFECT: invention improves efficiency of the extraction method and cuts the duration of the method.
