| titleOfInvention | Ferric arsenate @ polymer arsenic fixation material, preparation method thereof and arsenic fixation method of arsenic-containing solution |
| abstract | The invention belongs to the technical field of harmful waste treatment, and particularly discloses an iron arsenate @ polymer arsenic fixing material which comprises a core and a polymer coating the core, wherein the core is iron arsenate; the core is further preferably ferric arsenate coated with ferrous sulfide. The invention also provides a preparation method of the ferric arsenate @ polymer solid arsenic material and a method for preparing the ferric arsenate @ polymer solid arsenic material by adopting arsenic-containing wastewater. The invention discovers that the ferric arsenate @ polymer solid arsenic material with the core-shell structure has good stability, particularly stability under alkaline conditions, and is beneficial to reducing leaching toxicity. |
