Abstract
Water transport through an organic membrane is predicted using a growing emulsion globule described as a three-dimensional network. Osmosis occurs due to solubilization of water by inverse micelles that diffuse through the membrane phase. Solubilization experiments were carried out to determine the amount of water and sulfuric acid solubilizable by the surface active agents used. Surfactants were found to solubilize water and sulfuric acid by inverted micelles allowing transmembrane water flux from feed phase to receiving phase and transmembrane flux of sulfuric acid from receiving phase to feed phase. Parameters necessary for the mechanistic modelling of water transport have been measured using sophisticated techniques such as photon correlation spectroscopy, liquid scintillation spectroscopy and image analysis. Osmosis determined by batch experiments is compared to osmosis values predicted by a shell model.
