titleOfInvention | Preparation method of treatment material for heavy metals in sewage |
abstract | The invention discloses a preparation method of a treatment material for heavy metals in sewage, which comprises the following specific preparation processes: adding the epoxy adhesive adsorbent into an ethanol solution, stirring at normal temperature to form an emulsion, then adding diatomite into the emulsion, uniformly mixing, freezing by using liquid nitrogen and vacuumizing, then removing the liquid nitrogen, stopping vacuumizing, adding an thiosemicarbazide solution into a reaction container, gradually heating the reaction flask to room temperature under a sealed condition, then keeping the reaction flask at the room temperature for 3-4h, carrying out suction filtration and washing, and drying at 60-70 ℃ to obtain the porous load adsorbent. The treatment material prepared by the invention can be continuously used after adsorbing heavy metal ions and being eluted by hydrochloric acid, thereby realizing the recycling performance of the material, saving resources, reducing cost and reducing environmental pollution. |
