Abstract

The method for removing organic dyes from wastewater includes: (i) placing a magnetic polymer microsphere into contact with wastewater contaminated with organic dyes; (ii) permitting the organic dyes to adsorb onto the magnetic polymer microsphere; and removing the magnetic polymer microsphere using an external magnetic field applied by a magnet. The magnetic polymer microsphere has a ferromagnetic core surrounded by an adsorbent polymer.
