Abstract

A set of mathematical equations based on solute diffusion through membranes was developed. These differential equations were solved simultaneously using a numerical solution technique. The solute adsorption phenomenon, which creates large flux drops for polymer membranes, was investigated, accounted for in the mathematical model, and used in the computer program. The validity of the model was tested for single and multiple component systems using experimental data. The systems studied during this project were chloro- and nitrophenols in water. The concentration range was from 50 to 100 mg/L for each solute. High separations (up to 99%) for some ionized chloro-substituted phenolics were achieved.
