A new supported liquid membrane (SLM) was developed for the extraction of Europium (Eu) from nitrate medium. The idea was based on the SLM system with the sorbent interface. This membrane extraction system was a three-phase SLM consisting of an aqueous phase (feed phase), organic extractant/nano sorbent (membrane phase) and aqueous phase (stripping phase). For this purpose, the multi-walled carbon nanotubes (MV/CNTs) dispersed in the organic extractant (kerosene + Cyanex272) was held in the pores of a porous membrane by capillary forces and ultrasonic agitation. All experiments were performed using PTFE filter membranes. The results showed that loading of MWCNTs in the liquid membrane enhanced the permeation of Eu. Under the optimized extraction conditions, highest permeability coefficient value of 3.16 x 10(-5) m/s was observed for 0.60M Cyanex272 as carrier with 2 mg/ml CNTs, keeping the feed pH at 6 and 1 M HNO3 as stripping solution. The stability of the SLM was satisfactory at 10 cycles of operation. (C) 2015 The Institution of Chemical Engineers. Published by Elsevier B.V. All rights reserved.
