Modelling of mass transfer in facilitated supported liquid membrane transport of copper(II) using MOC-55 TD in Iberfluid

The transport of cooper(II) through a supported liquid membrane using MOC-5 5 TD (oxime derivative), dissolved in Iberfluid, as a carrier has been stud ied. A physico-chemical model is derived to describe the transport mechanis m which consists of: diffusion process through the feed aqueous diffusion l ayer, fast interfacial chemical reaction and diffusion through the membrane . The experimental data can be explained by mathematical equations describi ng the rate of transport. The mass transfer coefficient was calculated from the described model as 2.8 x 10(-3) cm s(-1), the thickness of the aqueous boundary layer as 2.6 x 10(-3) cm(-1) and the membrane diffusion coefficie nt of the copper-containing species as 1.2 x 10(-8) cm(2) s(-1).
