Abstract

Implementations herein relate to a method for preparing organic-pollution-resistant ion exchange resins and application thereof. The method includes adding modified inorganic particles to prepare novel ion exchange resins containing inorganic particles modified by a parcel modifier. A weight ratio between the monomer of the ion exchange resins and the modified inorganic particles is about 0.1% to 30%. The method may increase moisture content of the resins 3 to 30% such as to improve the structures of the resins, and therefore increase the regeneration efficiency 0.4 to 70%, as compared to conventions resins. The method improves resistance of resins to organic pollution, increases regeneration efficiency, and extends service life of the resins. In the process of water treatment, the ion exchange resin of the implementations may be regenerated with long-term stability. In addition to securing the water treatment efficiency, the method may avoid frequent replacement operations and lower the costs.
