多孔型聚苯乙烯系树脂的制备及其吸附性能的研究

onglobate polystyrene adsorbent has been prepared by cross linking suspension polymerization in this paper. By adding some polar monomer, such as methyl methacrylate, in the polymerization of styrene and divinylbenzene. The structure of adsorbents modified was characterized by means of physical technology and chemical methods. The methylene blue is adopted as adsorbate for the adsorption study, and explore the adsorbing time , pH , concentration of methylene blue as well as the adsorption temperature ,that effect on adsorption capacity .The results of experiments indicate that only do the pore radius resin have an important influence on adsorption process within a suitable pore size . The surface area will play an important role on adsorbing . The resin 2%MMA have a better adsorption result for methylene blue , and the experimental equilibrium data were fitted to the Fredunlich models.
