Strontium Isotope Effect in Liquid-Liquid Extraction of Strontium Chloride Using a Crown Ether
Isotope effects in a liquid-liquid extraction of strontium with dicyclohexano-18-crown-6 (DC18C6) were investigated. Unit mass enrichment factors were observed to increase with concentrations of strontium salt in an aqueous phase. Isotope distinguishing ability of DC18C6 to strontium isotopes was ca...
