  In this study, magnetic activated carbons (MACs) were synthesized by a chemical processing, adding iron (II and III) sulfates and alkali (aqueous NaOH solution) to the suspension of activated carbons at room temperature. Fine magnetite particles with some tens nanometer in diameter were precipitated on the surface of activated carbons. MACs prepared by this chemical precipitation processing could rapidly adsorb several pollutants such as bisphenol A and nonylphenol. In addition, MACs were easily collected with a permanent magnet and may be suitable for collection in a simple magnetic separation system.
