STUDIES ON ELECTROOSMOTIC PERMEATION BEHAVIOR OF METHANOL BENZENE MIXTURES USING PYREX MEMBRANES

Electroosmotic permeation studies across a pyrex membrane with and wit hout impregnation with aluminium hydroxide, using binary methanol-benz ene mixtures have been carried out. Variation of electroosmotic permea bility with composition has been examined. These results in conjunctio n with the membrane conductance measurements have been used to determi ne the electrical character of the membrane-permeant interphasial regi on responsible for electroosmotic activity. Attempt has also been made to examine the results in the light of intermolecular interactions am ongst the constituents of the mixtures.
