Title: Studies on Syntheses and Permeabilities of Special Polymer Membranes. 68. Analysis of Permeation and Separation Characteristics and New Technique for Separation of Aqueous Alcoholic Solutions through Alginic Acid Membranes
Abstract: Abstract Permeation and separation characteristics of methanol/water and ethanol/ water mixtures through an alginic acid membrane by a pervaporation method were investigated under various conditions. The permeation and separation characteristics for these aqueous alcoholic solutions were significantly different. To elucidate these different characteristics, a new combined evaporation and vapor permeation membrane separation technique, named “evapomeation,” was developed. The permeation and separation mechanisms for these two aqueous alcoholic solutions through the alginic acid membrane in pervaporation are discussed. Also, the permeation and separation characteristics for ethanol/water mixtures obtained by the evapomeation method are compared with those of pervaporation.
