Extraction of short-lived zirconium and hafnium isotopes using crown ethers: A model system for the study of rutherfordium

The extraction of zirconium and hafnium from hydrochloric acid media was studied using the crown ethers dibenzo-18-crown-6 (DB18C6), dicyclohexano-18-crown-6 (DC18C6) and dicyclohexano-24-crown-8 (DC24C8) as extractants...
