WebThe permeance of IPA solvent is generally lower than that of EtOH, as IPA is larger, more hydrophobic, and more viscous. These factors lower the diffusivity of IPA compared to that of EtOH. Therefore, in accordance with the solution-diffusion mode, the solute rejection profile in IPA is lower than EtOH for TFC membranes.
