摘要
本文研究了聚砜酰胺超滤膜制备的工艺条件和膜分离性能之间的关系。求得膜的分离性能随预压时间、蒸发时间、沉淀浴温度和溶剂种类而变化的规律。
In this paper, properties of ultrafiltration polysulfon-polyamide based membraneunder the different conditions of preparation were studied. Pure water flux and rejec-tion were evaluated as a function of prepressing time, evaporative time, precipitatingbath temperature and the kinds of solvent. The influenece of these variables on the per-formance of ultrafiltration membrans is reported.
