The hollow fiber composite membrane used in pervaporation test was prepared by dip coating method on the Polyether Sulfone hollow fiber using tartaric acid added PVA solution. And each membrane solution contains H2SO4 as acid catalyst for esterification reaction between PVA and TA. Also, to increase coating uniformity, specific amount of SDS(sodium dodecyl sulfate) was contained. Prepared membrane was characterized by IR spectroscopy, swelling to observe cross-linking degree of PVA and Tartaric acid then, finally used in pervaporation test. The pervaporation test was mainly studied about effect of catalyst amount in the membrane solution and the test was performed until pervaporation value converged.
