摘要
本文用葡聚糖作为标准物，考察了压力、线速度、原料浓度对中空纤维超滤膜表观截留率的影响。在测定表观截留率的基础上，以Ｌｅｖｅｑｕｅ公式和浓差极化公式计算了真实截留率。真实截留率受操作条件影响小，用它对表观截留率进行了校正，为建立中空纤维超滤膜截留率测定的规范化方法打下了基础。
The effect of operating conditions on the observed retention of hollow fiber ultrafiltration membrane was studied using Dextran as standardization sbustance. On the basis of the observed retention, the true retention was calculated by Leveque's equation and concentration polarization equation. It is obviously meaningful for the establishment of a standard method for the determinataion of retention of the hollow fiber ultrafiltration membrane.
