Transport and separation behavior of La(III) and Eu(III) in a plate type supported liquid membrane with DMDODGA as the carrier

Using DMDODGA as the carrier, the transportation and separation behavior of Eu(III) and La(III) were studied using a plate-type supported liquid membrane. La(III) and Eu(III) reach their maximum transport rates at feed phase nitric acid concentrations of 2 and 4 mol/L, which are 72.41 (± 2.12)% and 77.80 (± 2.45)%; Increasing the concentration of NO 3 − in feed phase will promote the transport of both ions. The change of HNO 3 concentration in feed phase had major effect on the separation of Eu(III)/La(III), and the co-transport of Eu(III)/La(III) was observed when the concentration of NO 3 − was 3 mol/L.
