Enhancement of the removal of lead ion Pb2+ from watrer using modified polysulfone membrane
Abstract
In this paper, polysulfone membranes were fabricated using two kinds of solvents, including N,N-Dimethylformamide (DMF) and Tetrahydrofuran (THF) by phase inversion method. The combination of graphene oxide (GO) and titanium dioxide (TiO2) nanoparticles in the matrix of membrane can also improve the hydrophilicity of prepared membranes. The membrane characterization was performed via the Scanning Electron Microscope (SEM), water contact angle (WCA), energy dispersive X-ray spectroscopy (EDX) and filtration test. The experimental results show that the removal ability of lead ion Pb2+ in water was improved because of the higher retention, water flux and higher antifouling resistance.
