Abstract: A hollow fiber (HF) membrane incorporating molybdenum trioxide (MoO3) nanoparticles. The membrane may be composed of PPSU hollow fibers that are coated or encrusted with MoO3 nanoparticles and can be made by dry-wet spinning. The hollow fiber membranes containing MoO3 nanoparticles remove lead, cadmium or other heave metals from waste water and are resistant to attachment of bacteria and fouling.

Abstract: A method of removing at least one cationic dye from an aqueous solution. The method includes contacting the aqueous solution with an adsorbent comprising a water-insoluble membrane disposed on a substrate. The water-insoluble membrane comprises cross-linked humic acid, at least one alginate, and hydroxyethyl cellulose. The contacting forms a treated aqueous solution having a lower concentration of the at least one cationic dye relative to the aqueous solution.
