研究了填料塔中牛血清清蛋白在聚乙二醇－硫酸铵双水相系统中的传质特性,测定了分散相含率和传质系数,用修正的HANDLOLS－BARON模型对实验数据进行关联,得到了相应的关联式,关联值与实验值相比,偏差小于5％.“,”The mass transfer characteristics of BSA solution in packed extraction column was primarily studied.Fractional dispersed phase hold up D and dispersed side mass transfer coefficients k D a for BSA in PEG (NH 4) 2SO 4 aqueous two phase system(ATPS) were measured.The average deviation is within 5%in three ATPS between experimental and calculated k D a by modified Handlos Baron model.
