摘要

The present work is proposed to evaluate the potential of using an integrated pervaporation process to separate water-rich acetic acid mixtures. This integrated pervaporation process based on a simple PDMS membrane with a combination ofhydrophobic ionic liquid which are molten comprised of an array of heterocyclic cations and various anions. A hydrophobic ionic liquid phase is introduced as the third phase between the water phase and the solid PDMS membrane phase for improving the selectivity and mass transfer of acetic acid from its aqueous matrix. The feed temperature as an important operation condition was investigated in this work. The primary results show that the ionic liquid as an extractant prior to the pervaporation process is favorable for improving significantly the selectivity and permeating flux of acetic compared with the PDMS pervaporation process. This performance could be attributed to the acetic acid concentrated in ionic liquid phase prior to the permeate by pervaporation. A sample of an antibiotic pharmaceutical effluent was investigated using the above integrated pervaporation process, and the result suggests that this integrated pervaporation process can be developed to an industrial scale for recover acetic acids from water-rich effluent.
