摘要:
以聚醚砜中空纤维膜为支撑膜,通过界面聚合方法制备了能有效传递电解质而截留低分子量有机物的复合荷电镶嵌膜.将均匀设计用于界面聚合制备荷电镶嵌膜的过程中,用SPSS软件进行数据处理,得到了回归方程,方程描述了各种因素对膜分离性能的影响.在实验范围内,酸接受剂浓度对膜分离因子的影响很小;4-氯甲基苯酰氟浓度和表面活性剂浓度可取最大值;聚乙烯亚胺浓度和界面聚合反应时间存在交互作用和最优值.模型计算值与实验结果吻合良好,表明该模型可用于指导成膜实践.在优化条件下,膜对无机盐的截留率不超过30%,膜对蔗糖截留率大于90%,对二甲酚橙的截留率可达96%,说明该膜可用于无机盐与低分子量有机物的分离.
Abstract:
Using polyethersulfone hollow fiber membrane as the support film, a composite charged mosaic film that can effectively transfer electrolyte and retain low molecular weight organic matter was prepared by interfacial polymerization. The uniform design was used for the process of preparing charged mosaic membranes by interfacial polymerization, and the regression equation was obtained by using SPSS software for data processing, which described the influence of various factors on the separation performance of the membrane. In the experimental range, the acid acceptant concentration had little effect on the membrane separation factor; 4-(chloromethyl)benzoyl fluoride concentration and surfactant concentration can be maximumed; There was an interaction between polyethyleneimine concentration and interfacial polymerization reaction time. The calculated values of the model are in good agreement with the experimental results, indicating that the model can be used to guide the practice of film formation. Under the optimized conditions, the interception rate of membrane to inorganic salts does not exceed 30%, the interception rate of membrane to sucrose is greater than 90%, and the interception rate of p-xylenol orange can reach 96%, indicating that the membrane can be used for the separation of inorganic salts and low molecular weight organic matter.
