| Abstract: | The primary goal of this paper is to report the results of solvent evaporation time on the morphology and gas permselective properties of asymmetric CAB membrane. It was found that the solvent evaporation time of the casting solution which is suitable for the preparation of the asymmetric membrane, could be determined by the components in the remaining solvent. The main evaporating solvent and the remains in certain stages of the evaporation process have been studied by FT-IR. |
