In present research, novel asymmetric polysulfone (PSF)membraneswith high hydrophilicity and noticeable rejection of arsenic, as one of the major environmental problems, were prepared from PSF/Brij-58/NMP (1-methyl-2-pyrrolidone) ...

time on the efficiency of arsenic removal. Up to 88% removal efficiency for arsenic was obtained by nanoparticles dosage of 40 mg/L at time equal to 30 min and pH 7.5. It could be concluded that the removal efficiency was enhanced by increasing CaO2...
