Application of topological indices for description of pertraction in an agitated bulk liquid membrane system

The pertraction of benzoic acid in a bulk liquid membrane (BLM) was investigated. The effect of membrane solvent and presence of carrier (tri-noctylphosphine oxide TOPO) was examined. The liquid membrane was composed of hexane, heptane, octane, nonane, decane or dodecane. The results of experiments indicated that some selected topological indices of the membranę components can be used for quantitative description of linear correlation between fluxes and structure of organic solvent

Bond-graph description and simulation of membrane processes: dependence of ablm efficiency on liquid membne volume

Network thermodynamic analysis was used for bond-graph representation of simple pertraction in the agitated bulk liquid membrane. The output flux dependence on the membrane volume was analysed and compared with the same dependence observed experimentally for pertraction of benzoic acid

Transport and separation of Zn(II) and Cu(II) in an agitated bulk liquid membrane

Pertraction of Zn(II) and Cu(II) ions from binary solutions across a bulk liquid membrane (BLM) containing di(2-ethylhexyl)phosphoric acid (D2EHPA) as the carrier was investigated. The influence of the pH, D2EHPA concentration, feed and stripping phase concentration was evaluated. The enhancement of the separation effects in unsteady state pertraction of Zn(II) was observed
