✦ Synopsis
Unlike non-charged macromoles, the general unsteady state convection-diffusion equations associated with the osmotic theory do not allow accurate prediction of the ultrafiltration or reverse osmosis in unstirred batch cell of charged solutes. According to the results obtained with total retention of bovine serum albumin, we postulate a modification of the physicochemical environment of the solute in the boundary layer like the osmotic pressure. However, for reach solute a new set of osmotic pressure data allows to simulate accurately all the experiments performed with alike concentration profiles,
