Název v původním jazyce

Extraction of Calcium and Strontium into Phenyltrifluoromethyl Sulfone by Using Synergistic Mixture of Hydrogen Dicarbollylcobaltate and ?Classical? CMPO

Popis výsledku v původním jazyce

Solvent extraction of microamounts of calcium and strontium by a phenyltrifluoromethyl sulfone (FS 13) solution of hydrogen dicarbollylcobaltate (H+B?) in the presence of octyl-phenyl-N,N-diisobutylcarbamoylmethyl phosphine oxide (?classical? CMPO, L) has been investigated. The equilibrium data have been explained assuming that the species HL+,HL2+, ML2+, ML22+ and ML32+ (M2+ = Ca2+, Sr2+) are extracted into the organic phase. The values of extraction and stability constants of the cationic complex species in FS 13 saturated with water have been determined. In the considered FS 13 medium, it was found that the stability constants of the complex species CaLn2+, where n = 1, 2, 3 and L is ?classical? CMPO, are higher than those of the corresponding complexes SrLn2+.
