METHOD OF REDUCING CONTAMINANTS IN WATER

摘要

This invention relates to a method for preparing a nanotubular composite matrix for reducing contaminants in water and on the matrix's surface including the steps of preparing a photocatalytic agent in nanotubular form; dissolving an antimicrobial agent in a solvent; impregnating the photocatalytic agent with the antimicrobial agent in solution to form a matrix; removing excess solvent from the matrix; and calcining the matrix to remove a moiety of the antimicrobial agent to form the nanotubular composite matrix. The invention further relates to a method for reducing contaminants in water including the steps of providing a nanotubular composite matrix; incubating the water in the matrix; and activating the photocatalytic agent by exposing the matrix to a light source. The applicant has found that the method according to the invention reduces contaminants in water within 15 minutes in the presence of sunlight.
