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

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.

A method for N-formylating an amine that includes reacting the amine and a formamide compound in the presence of a phosphonic anhydride to form an N-formylated amine. The phosphonic anhydride is present in an amount of 5-100 mol % relative to a total number of moles of the amine, and the reacting is performed for 1-24 hours at a temperature of 45-100&#xb0; C.
