Polyamide Forward Osmosis Membrane: Synthesis, Characterization and Its Performance for Humic Acid Removal

In this research, modification on ultrafiltration (UF) membrane by synthesis of a thin layer of polyamide selective layer was designed for high performances of forward osmosis (FO)water treatment. Two monomers, m-Phenylenediamine (MPD) and Trimesoyl chloride (TMC) with different concentration of MP...
