| titleOfInvention | Industrial preparation method of iron oxide resin composite adsorbent |
| abstract | The invention discloses an industrial preparation method of an iron oxide resin composite adsorbent, belonging to the field of industrial production of composite resin adsorbents for wastewater treatment. The preparation method comprises the steps of (A) adding strongly basic anion resin into an iron salt solution in batches, stirring, (B) filtering, and recycling and sleeving the filtrate in the step (A); (C) adding the filter residue obtained in the step (B) into a sodium hydroxide solution in batches for reaction, and filtering; (D) adding NaOH into the filtrate in the step (C), and mechanically applying the NaOH to the filtrate in the step (C); (E) and (C) washing the filter residue in the step (C) by using a sodium chloride aqueous solution and water, filtering and drying. In the industrial preparation method of the Fe (III) -immobilized strong-base anion resin adsorbent, the ferric salt solution, the alkali liquor, the acid liquor and the like can be recycled, so that the production cost and the environmental pollution are greatly reduced, the method conforms to the national industrial policy of energy conservation and emission reduction, and is suitable for industrial popularization. |
