Emulsion liquid membrane pertraction of L-lysine from dilute aqueous solutions by D2EHPA mobile carrier

Study of the influence of solute and carrier characteristics on facilitated pertraction mechanism in pseudosteady-state conditions

“…The liquid membranes can be obtained either by emulsification, but their stability is poor [1][2][3][4][10][11][12][13], by including the solvent in a hydrophobic porous polymer matrix [1,2,5,8,[14][15][16][17][18], or using pertraction equipments of special construction, which allow to separate and easily maintain the three phases without adding surfactants (free liquid membranes) [7,[19][20][21][22].…”

Mass Transfers Within Emulsions Studied by Differential Scanning Calorimetry (DSC) - Application to Composition Ripening and Solid Ripening

“…A carrier is a molecule which can form a complex with the toxic compound at the external interface and transport it to the internal phase where the toxic compound will be entrapped (Hasan et al, 2006;Frasca et al, 2009). High selectivity means that the carrier holds a good affinity with the toxic compound in order to exclusively transport it through the membrane (Kaghazchi et al, 2006). In separation applications, the instability of the multiple emulsions can reduce significantly the efficiency of the process.…”

Separation of cadmium(II) from spent nickel/cadmium battery by emulsion liquid membrane

“…Emulsion liquid membrane (ELM) is an attractive alternative because of its high efficiency and low energy consumption (Correia and Carvalho, 2000;Juang and Wang, 2002;Lee and Lee, 2005;Kaghazchi et al, 2006;Kumbasar and Tutkun, 2008). Liquid membrane can accomplish both extraction and stripping in one step.…”
