Abstract

Novel polyvinyl chloride grafted poly (ethylene imine), PVC-g-PEI membranes have been successfully synthesized by solvent evaporation technique using THF/ethanol as a solvent mixture. PEI was incorporated into PVC in different portions to increase the weak hydrophilicity of PVC membranes and to enhance physicochemical membranes surface properties. Membranes preparation conditions of PVC-g-PEI and their applications for water desalination process were optimized and discussed in details. PVC-g-PEI membranes were characterized by FTIR, morphologically using SEM, thermally using TGA&DSC, and mechanically using universal testing machine. Poly (ethylene glycol), PEG was then added to PVC-g-PEI membranes as a pore forming additive to increase pores density area and improve efficiency of the permeation flux of membranes. Addition of PEG portions increased permeation flux of PVC-g-PEI membranes (452 L/D/M2513 L/D/M2and605 L/D/M2) and salt rejection performance for mono membrane (33.5%, 30.8%and 27.4 %) for 3%, 2% and 1% NaCl solutions, respectively. Ion Exchange Capacity (IEC) for (PVC-g-PEI) membrane was 2.3 meq/gm and water uptake was 23%.All filtration experiments results were carried out at a trans-membrane pressure of 0.3 MPa at room temperature. The results showed that the permeate quality and quantity almost stable upon long run, thus PVC-g-PEI membranes can be used effectively for water treatment applications e.g. Nano-filtration and desalination.
