Original language name
Solvent extraction of radioactive Cs+ by hydroborate anionic extractants of the [1-LB10H9]-type (L = amine or phosphine)
Original language description
New anion derivatives of the closo-decaborate [B10H10](2-) bearing amine or phosphine groups were tested for the extraction of radioactive cesium cations in acidic medium. The technique used is the liquid-liquid extraction based on the complexation of Cs+ by these anions to form neutral compounds which are extracted by organic solvents (diluents) of medium polarity. Promising results were obtained with the anion [1-(C6H5CH2)(2)(C6H5)NB10H9](-) (3) soluble in many organic solvents. The most efficient diluent for the extraction is nitrobenzene. Using hydrochloric acid or sulfuric acid in the aqueous medium instead of nitric acid does not significantly affect the efficiency of Cs+ extraction.
