Abstract

Characterization and control of membrane-based separation or drug delivery systems require the development of noninvasive methods for measurement of membrane hydration during the process of interest. In this paper, real time fluorescence methods which were developed in order to study such membrane systems are described, and data which demonstrate their sensitivity and speed are presented. Sensitivity and speed were sufficient that transient phenomena such as diffusion lag time and Donnan distribution effects caused by changes in fixed charge density were well resolved.
