The development of the model of a small-sized extractor with self-control interface level to divide a pair 99Мо/99mТс

Abstract

The authors have proposed a construction of a model of a small-sized extractor with self-control interface level to separate 99mТс from molybdenum; the calculations for model have been carried out. The extractor construction makes it possible to carry out multiple cyclic extractions in a small enclosed volume. In a pilot model 99mТс yield into organic phase is more than 80 % at triple tandem cycle when the volume ratio of organic and water phases exceeds 1. Extractor small size predetermines the development of mobile extraction units and their application in medical centers.
