Article Preview

Wet phase inversion is used to prepare and control morphology of membrane based on PEEKWC in DMA at 14wt %. A comparison study has been done with Polysulfone and PVDF as basic materials for membrane preparation. The effect of the coagulant bath is studied by using water and ethanol as nonsolvent. Excepting for PVDF, the micrographs shows that no strong effect in the structure of the membranes. The macro-voids still exist but less numerous and large in the case of membrane immersed in ethanol coagulant bath. Microporous membrane in some cases was obtained. These membranes were used in supported liquid membranes experiments for Ni(II) metal ions transports using 2-diethyl hexyl phosphoric acid (D2EHPA ) as carrier.
