Development of UF membrane by coating using green synthesized copper oxide nanoparticle for remediation of heavy metals

Abstract

Copper Oxide Nanoparticles were green synthesized using extracts of Anabaena variabilis. The synthesized nanoparticles were washed, dried and kept for further use. Samples were characterized in terms of X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Field Emission Scanning Electron Microscope (FESEM), Energy Dispersive X-Ray Spectroscopy (EDS), Brunauer-Emmett-Teller (BET) etc. Average crystallite size of Nano powders was calculated from full width at half maxima of XRD Peaks. Debye-Scherrer formula was used for the calculation of crystallite size which was found to be 22.0684 nm. Spherical morphology of the NPs was confirmed from FESEM micrographs. BET surface area of CuO NPs was 3.718 m2/g. Phthalates and Paraben were used to observe removal efficiency of synthesized CuO NPs. CuO nanoparticle was used for development of UF ceramic membrane by coating on inside wall of 300mm length ceramic support (OD/ID 10/7 mm). BET Surface area of unsupported membrane was determined to be 6.355 m2/g. Flux Values of 249LMH and 230LMH for Phthalates and paraben respectively was obtained after 120mins of filtration study. Removal Efficiency of 92% & 96.3 % for phthalates and paraben was obtained.
