Iron oxide nanoparticles were incorporated to form composite microspheres of SiO₂ and Fe₂O₃ for magnetic separation of the particles after adsorption or photochemical decomposition. Economic material, sodium silicate, was purified by ion exchange to prepare aqueous silicic acid solution, followed by mixing with iron oxide nanoparticles. Resulting aqueous dispersion was emulsified, and composite microspheres of SiO₂ and Fe₂O₃ was formed from the emulsion droplets as micro-reactors during heating. Removal of methylene blue using the composite microspheres was performed by batch adsorption process. Synthesis of composite microspheres of silica containing Fe₂O₃ and TiO₂ nanoparticles was also possible, the particles could be separated using magnets efficiently after removal of organic dye.
