Formation Of Polythersulfone (PES) Membrane With Silver Nitrate (AgNo3) Mixture Characteristics, Mechanical Properties And Water Treatment Performance

This research will be used as raw material for making Polyethersulfone (PES) polymer membranes. The properties of the membrane are known by knowing the characteristics of the membrane which can determine the effectiveness and efficiency of the membrane made by testing the parameters. The parameter studies used are tensile strength, microstructure, and membrane permeability. This membrane was made using three different concentrations of Polyethersulfone (PES) solution (15%, 20%, 30% by weight) with the addition of 1% silver nitrate (AgNO3) concentration and N,N-Dimethylformamide (DMF) as a solvent. The membrane formation method is phase inversion. The method used is phase inversion, in which the polymer, reinforcement, and solvent are mixed homogeneously for about 2-3 hours, and the membrane is directly printed on a glass plate. Three tests were conducted for membrane formation: tensile test, microscopic test using scanning electron microscope, and flux value test using clean water permeability (CWP). This study concluded that membrane expansion by increasing the concentration of polyetherculfones at concentrations of 15 wt%, 20 wt% and 30 wt%, and 1 wt% Silver nitrate can increase the tensile stress and pore density on the membrane surface.
