REMOVAL OF VOCs FROM THE AQUEOUS SOLUTIONS BY PERVAPORATION USING A FILLING-TYPE MEMBRANE

  

Abstract: The membranes were prepared by the incorporation of highly hydrophobic silicalite and carbon molecular sieves (CMS) from different precursors into the PDMS casting solutions. The pervaporative removal of VOCs, such as benzene, from aqueous solutions was carried out using the separation factor and permeation flux as the evaluating parameters. The effects of the CMS types and structures, feed concentrations on the pervaporation performance were preliminarily investigated.
