The Structure and Properties of Macroporous Ion Exchange Resins and New type of Adsorbents

In the studies of this item, the paper contains three parts: the first part was the discovery of the synthesis of polystyrene macroporous ion exchange resins; the second part was to study the preparation of the macroporous resins in the presence of inert solvent of different properties; the third part was the investigation of the relationship between the structures and the properties. Based on the studies, it was proved that the properties of the macroporous resins possessed radioresistance, good ion exchange reaction kinetics and excellent mechanical strength. The macroporous ion exchange resins were not only exchanging very well with the inorganic ions, but also could be used for decolorization, catalyst and purification of organic substances. The macroporous resins without functional groups could be used as polymeric adsorbents. They can be used for the extraction and purification of natural products and also be used for antibiotics production, blood hemoperfution, environmental protection, etc. The macroporous ion exchange resins and adsorbents mentioned above have been produced and widely applied in chemical industry, medicine production, environmental protection, medical treatment, analysis and so on.
