  • Hydrophilic magnetic resin with high specific area, preparation method therefor and application method thereof for rapidly extracting phthalates in water body
    Patent number: 10010862
    Abstract: Implementations herein relate to a method for extraction of phthalates using hydrophilic magnetic resins with high specific surface areas. The implementations relate to a technical field of preparation of resins for fast enrichment and separation of trace organics in water. By adding magnetic particles, precursor resins may be prepared using divinylbenzene, vinyl benzoate and glycidyl methacrylate copolymerization ester. After the cross-linking reaction, surface areas of the resins are increased and hydrolysis of the ester group in alkaline solution may be implemented to obtain high specific surface magnetic resins rich in hydroxyl groups. The resins have higher adsorptive capacity and selectivity to adsorb phthalates in water samples. Rapid extraction may be implemented using magnetic solid phase extraction rod to achieve enrichment and separation of phthalates in a large amount of water samples.
