Kinetics of Sm3+ extraction by BTMPPA using single drop technique

The rate of Sm(III) extraction from acidic nitratc-acctato medium by bis(2,4,4-trimelhylpentyOphosphoric acid (Cyancx 272, BTMPPA, H2A2) in toluene has been measured by the single drop technique. The rate of mass transfer per unit area is found to be proportional to [Sm3*], [ H2A2](0>, [H*] at th...
