Abstract
Thin film composite (TFC) polyamide membranes have been used and progressed for desalination and pressure retarded osmosis. A preparation method of TFC polyamide nanofiltration (NF) membranes with enhanced flux is reported. The polyamide TFC NF membrane was fabricated by adding tributyl phosphate (TBP) and triphenyl phosphate (TPP) to an organic solution containing trimesoyl chloride (TMC) during an interfacial polymerization process. The membrane test was performed using a 2000ppm of sodium chloride solution and a cross-flow permeation cell. The addition of TBP to the TMC organic solution exhibited much higher water flux than that of TPP. The resulting membrane using TBP showed a remarkably increased water flux and a slightly reduced rejection of sodium chloride. From SEM and AFM data, the surface morphologies of the TFC polyamide NF membranes were considerably changed compared to the membrane prepared without addition of TBP in the TMC organic solution.
