【Abstract】 Purification of millet wine by pelysulfone and pelysulfonamide ultrafiltration membrane is discussed.Suspension particles with diameters of 0.15—4 μ and macro-molecular organic organic substances are identified.The color,odor and taste of the filtrated millet wine are better than that of the unparified.The filtrated millet wineis in accordance with the demands shown by physical and chemical analysis. Polysulfone membrane after immersion in millet wine for six months still keeps its chemical stability.更多还原
