| titleOfInvention | Modified cation-exchange resin and its preparation method and application |
| abstract | The invention discloses a kind of preparation method of modified cation-exchange resin, wherein, the preparation method includes：Cationic ion-exchange resin is positioned in stannous sulfate solution to soak and taken out after 15 32h, Resin A 1 is obtained；Resin A 1 is placed in sodium hydroxide solution and adds strong oxidizer and soaks taking-up after 3 10h, Resin A 2 is obtained；Resin A 2 is dried, modified cation-exchange resin is obtained；Wherein, relative to the cationic ion-exchange resin of 100 parts by weight, the consumption of the stannous sulfate is 20 100 parts by weight, and the consumption of the sodium hydroxide is 0.5 20 parts by weight, and the consumption of the strong oxidizer is 0.1 10 parts by weight.After the present invention is by the way that cationic ion-exchange resin is soaked in stannous sulfate solution, it is positioned over again in sodium hydroxide solution and adds strong oxidizer, obtained modified cation-exchange resin is set to carry out degradation treatment to methylene blue, and handling rate is higher, and can be recycled. |
