Method of removing organic pollutants from water using ball milled and sonicated oil fly ash powder

Abstract

A method of removing an organic pollutant from water by contacting the water with a ball milled and sonicated oil fly ash powder to adsorb the organic pollutant onto the ball milled and sonicated oil fly ash powder. A method of producing a ball milled and sonicated oil fly ash powder involving ball milling oil fly ash to provide ball milled oil fly ash particles with an average particle size of less than 1 μm and sonicating the ball milled oil fly ash particles in an aqueous medium to form the ball milled and sonicated oil fly ash powder. A method of improving recovery of valuable metals/elements from oil fly ash.
