-
摘要: 将多元回归设计应用于聚醚砜超滤膜的制备,得到了截留率、水通量与可变因子之间的回归模型和铸膜液的最优组合设计。经实验验证,模型计算值与实验值基本吻合。Abstract: The multifactorial regression design was applied to the study of the polyether-sulfone ultrafiltration membranes, and the regression models of the relation between cut-off molecule weight or water flux and variable factors were obtained.The optimum combination design was obtained too. The values calculated with the model agree well with the experimental results.
