Abstract

The pervaporation separation experiments of phenol-water mixtures were carried out by using Type 1 (PDMS : crosslinking agent= 1 : 0.25) and Type 2 (PDMS : crosslinking agent= 1 : 0.35) silicone rubber membranes at 30, 40 and $50^{\circ}C$. The phenol concentrations in the feed to be separated were 500 ppm to 5 wt%. Type 2 membranes were more efficient than Type 1 membranes for the separation of phenol-water mixtures. The phenol concentration of 70wt% was obtained for 5wt% of phenol concentration in the feed at $30^{\circ}C$ and 11wt% phenol concentration observed for 500ppm of phenol concentration in the feed at $30^{\circ}C$ by using Type 2 membranes.
