COMPOSITION OF EXTRACTION-CHROMATOGRAPHIC MATERIAL FOR SELECTIVE EXTRACTION AND PURIFICATION OF PROMETHIUM-147 FROM ACCOMPANYING RARE-EARTH ELEMENTS FROM NITRIC ACID SOLUTIONS Russian patent published in 2016 - IPC C07F9/40 C22B3/24 C22B60/00

Abstract RU 2574595 C1

FIELD: chemistry.

SUBSTANCE: invention relates to compositions of extraction-chromatographic materials of impregnated type for selective extraction and purification of promethium-147 from accompanying REE from nitric acid solutions, which consist of two components with the following content: 1-50 wt % phosphorylpodand - derivative of 1,5-bis[2-(oxyalkoxyphosphoryl)-4-(ethyl)]phenoxy-3-oxapentane of formula , wherein R represents alkyl C₃-C₁₂, and 99-50 wt % of macroporous spherically granulated copolymer of styrene with divinylbenzene with granule size 40-400 mcm.

EFFECT: composition of novel highly effective extraction-chromatographic material for selective extraction and purification of promethium-147 from accompanying REE from nitric acid solutions.
