The monodisperse oil-in-water (O/W) emulsions were prepared by using a glass capillary tube to build a single-stage microfluidic device. The Poly (methyl methacrylate/dimethylaminoethyl methacrylate)[P(MMA/DMAEMA)] porous microspheres were successfully prepared by free radical polymerization under UV irradiation using the emulsion as a template. The particle deviation coefficient (CV) value of the microspheres was less than 5%, indicating the good monodispersity. The adsorption mechanism, regenerative adsorption property and adsorption property of prepared porous microspheres for Cr(VI) were investigated. The results showed that the pH have a great influence on the adsorption rate of microspheres. The microsphere adsorption conforms to the quasi-secondary kinetic model and belongs to the chemical adsorption. Meanwhile, the microsphere isotherm adsorption conforms to the Langmuir model and belongs to the monolayer adsorption.
