- Abstract
Coprecipitation of 137Cs and 85Sr with [Na(18-crown-6]BPh4 solid phase from aqueous, aqueous-ethanolic, and alkaline solutions is studied. 137Cs and 85Sr cocrystallize with [Na(18-crown-6]BPh4 from aqueous and aqueous-ethanolic solutions. The cocrystallization coefficients D of 137Cs and 85Sr from aqueous solutions are 2.6±0.5 and 3.3±0.3, respectively. For aqueous-ethanolic solutions, the corresponding values are 4.4±0.5 and 3.4±0.4. In the alkaline solutions (0.1 and 1 M NaOH), 54–74% of 137Cs and 37–51% of 85Sr pass into the [Na(18-crown-6]BPh4 solid phase, depending on the crown ether concentration in the system.
