Preparation and Characterization of Interfacially Polymerized Polyamide Membrane for Dye Removal

Interfacial polymerization of polyamide was conducted using hydrophobic and hydrophilic membrane support. The effects monomer concentration were investigated, the resulting thin-film composite membranes tested for their performance in dye removal different flow configurations. results showed that a dense layer successfully formed on support, while with very loose structure became smoother more as trimesoyl chloride increased, leading to increased permeate flux reduced rejection. highest sunset yellow rejection 45.7% 4.9 L/m2.h obtained when from 0.05 w/v% (a high amine acid ratio 20) filtration cross-flow configuration.
