ZEOLITE-FILLED PDMS MEMBRANES .1. SORPTION OF HALOGENATED HYDROCARBONS

Aiming at a more thorough understanding of the influence of zeolite fi llers in PDMS membranes on the pervaporation of chlorinated hydrocarbo ns from aqueous solutions, the sorption aspect of this separation proc ess was studied. Firstly, the sorption of water and five different chl orinated hydrocarbons was investigated in the zeolite and the polymer separately. Secondly, the composite system was considered and conclusi ons were drawn concerning interactions at the zeolite-polymer interpha se. Finally, the sorption results obtained on the self-synthesized mem branes were compared with measurements on commercially available PDMS membranes (GFT).
