摘要：

NF membranes have been prepared from , , -cyclodextrin (CD) composite with polysulfone and characterized by pore size, thickness, pure water permeability, contact angle measurement and membrane morphology study. The permeation performances of the prepared membranes have been tested for separation of acetic acid from dilute aqueous solution. Effect of concentration, pressure, flow rate on flux and rejection have been calculated and interpreted. Different permeation models have been tested for experimental values and validated by comparing the values with the experimental data. It has observed that in -CD membranes 99% recovery of acetic acid from aqueous solution has been obtained and found to be the best membrane for separation of acetic acid from dilute solution.
