| Abstract: | The transport of copper(II) through a supported liquid membrane using MOC-55 TD (oxime derivative), dissolved in Iberfluid, as a carrier has been studied. A physico-chemical model is derived to describe the transport mechanism which consists of: diffusion process through the feed aqueous diffusion layer, fast interfacial chemical reaction and diffusion through the membrane. The experimental data can be explained by mathematical equations describing the rate of transport. The mass transfer coefficient was calculated from the described model as 2.8×10?3 cm s?1, the thickness of the aqueous boundary layer as 2.6×10?3 cm?1 and the membrane diffusion coefficient of the copper-containing species as 1.2×10?8 cm2 s?1. |
