Regeneration Research of Porous Magnetic Microspheres during Treatment of Wastewater Containing Cationic Dyes

• The application feasibility of porous magnetic microspheres in the removal of cationic dyes from wastewater was investigated. Various desorption solutions were employed for the recovery of cationic dyes from absorbents and regeneration of porous magnetic microspheres. The results showed that 1M NaCl or 1M KCl in water/methanol co-solvent had excellent desorption ability for methyl violet. This fact was further demonstrated in the removal cationic gold yellow from its aqueous solution. Overall, this provided a simple methodology for the treatment of wastewater containing cationic dyes and the regeneration of porous magnetic microspheres.
