Abstract |
The effect of solute asymmetry and in turn solute surface activity on flux-limiting membrane interactions was studied in a 6 cell, duplex, continuous flow-through ultrafiltration test loop. Triton X-100, sodium dodecylbenzenesulfonate, and Carbowax 600 were chosen as the model nonionic surfactant, anionic surfactant, and nonionic symmetrical solute respectively. The results of these studies were used to correlate observed flux-limiting and solute rejection effects with the membrane type and the surface-active properties of the solute.
