Abstract: SummaryThe transport of urea and other biologically interesting solutes in aqueous solution across poly(2-hydroxyethyl methacrylate) (p-HEMA) hydrogel membranes has been studied. The results show that p-HEMA membranes have a high permeability to urea due to a strong interaction between the polymer and urea, and, in addition, they are consistent with a pore flow model in which solute transport takes place through water-filled regions essentially unaffected by the surrounding polymer matrix. The results indicat…
