| dc.description.abstract | Novel blended membranes of Polyvinyl chloride-co-vinyl acetate /Polyethylene glycol PVCA/PEG with various ratios of tetraethyl ortho silicate (TEOS) and Halloysite nanoclay were synthesized through solution casting methodology for reverse osmosis water desalination. The functional group analysis, water content percentage, antibacterial activity, permeation flux and percentage of salt rejection are observed for Reverse Osmosis (RO) purposes. Optical density (OD) of control and modified membranes of both series indicated characteristic values, which inhibit the growth of bacteria. FTIR analysis, confirmed the existence of different groups which give specific broad peak value of O-H stretching band observed at 3650-3250 cm1 in both series. The control and modified membranes of PPAH-6 to PPAH-10 series showed broad band of N-H stretching at 3500-3360 cm1. Furthermore, C-Cl was observed at 730-550 cm1 due to the presence of vinyl chloride group in PVCA copolymer membrane series. | |
