Abstract

Three different sieving coefficient definitions were theoretically investigated. It has been shown that the local sieving coefficient, characterizing membrane property, can be calculated under specified assumptions from input-output measurements. In contrast, the evaluation of the device sieving coefficient, useful in kinetic modeling, is validated in a situation in which calculation of the local sieving coefficient is connected with substantial error. The relationship between different sieving coefficient definitions is also given.

摘要

理论上研究了三种不同的筛分系数定义。结果表明，表征膜性能的局部筛分系数可以在特定假设下根据输入-输出测量值进行计算。相比之下，在动力学建模中有用的装置筛分系数的评估，是在局部筛分系数计算存在较大误差的情况下得到验证的。还给出了不同筛分系数定义之间的关系。
