Abstract

A hollow fiber based liquid membrane impregnated with organic solvent M5640 diluted with kerosene is an attractive method to extract copper from low copper content (500ppm) industrial wastewater. The flow rate of the feed solution affects the permeability of the membrane. The optimum flow rates of the stock solution and strip solution were 2080 mL/h and 6264 mL/h, respectively. It can be considered that under the above conditions the resistance to mass transfer was close to the minimum due to the small thickness of the diffusion boundary layer.
