| titleOfInvention | Method for removing mercury ions in water and regeneration method of adsorbent used in same |
| abstract | The invention relates to a method for removing mercury ions in water and a regeneration method of an adsorbent used in the same. An adsorbent is put in water to be treated to adsorb mercury ions in the water. The adsorbent is a palladium nanoparticle supported/iron oxide magnetic modified carbon nanotube composite material. The carbon nanotube composite material provided by the invention has nano structure and large specific area; and after the carbon nanotube composite material is oxidized and activated, carboxyl group, hydroxyl group and other active functional groups are formed on the surface of the carbon nanotube composite material, thereby enhancing the hydrophilic property and the adsorptive capacity for positively charged metallic ions. The iron oxide is coated on the surface of the activated carbon nanotube composite material, and therefore, the activated carbon nanotube composite material has strong soft magnet property, and can easily implement solid-liquid separation of the adsorbent and the polluted water body under the action of an external magnetic field. The palladium modification strengthens the affinity of the composite material with mercury ions, and greatly enhances the adsorption capacity and selectivity of the original carbon nanotube composite material for mercury ions (the maximum adsorption capacity is 55.3mg/g). |
