Abstract

The design was developed and the calculations were performed for a small-size extractor with self-controlled level of the boundary of the aqueous and organic phases for multiple cyclic extraction in a closed volume. With an experimental model 12 cm high and 3.5 cm in diameter, it was demonstrated that, at the volume ratio of the organic and aqueous phases exceeding 1, the 99mTc yield exceeding 80% is attained in a triple coupled cycle. Small size of the extractor creates prerequisites for the development of mobile extraction instal-lations which can be used directly in medical radiological laboratories.
