Europium (II) from product solution of Bangka Monasit mineral destruction has been succesfully separated from other rare earth elements such as La, Nd, Pr, Gd, Yb and Lu using cascaded supported liquid membrane technique. The first treatment was reduction process of Eu3+ to Eu2+ using Jones reductor. Optimation of supported liquid membrane consists of pH variation of feed phase, carrier composition TBP:D2EHPA in membrane phase, rare earth elements concentration in feed phase and acid concentration in receiving phase. The best condition obtained for this supported liquid membrane process was pH feed phase = 3; carrier composition in membrane phase TBP:D2EHPA 0.25 M:0.75 M and rare earth elements concentration in feed phase of 203.84 ppm and HCl concentration in receiving phase was 3 M. In the condition after transport process during 300 minute europium purity gained was 76. 174 % with 51.79 % rendemen. |
