## (57) ABSTRACT 

A method is disclosed for synthesizing nano filters for water treatment. The method includes: dispersing an active bind› ing agent in an organic solvent solution to create a suspen› sion of the active binding agent and the solution of the solvent; dissolving an organic polymer resin and an anionic surfactant in the suspension of the active binding agent and the solvent solution to create a sol gel; and electrospinning the sol gel to form electrospun nanofiber composites with embedded, surface-active nanoparticles.
