| titleOfInvention | Lead ion adsorbent and preparation method thereof |
| abstract | The invention discloses a lead ion adsorbent and a preparation method thereof, and particularly belongs to the field of lead ion adsorbents. The invention relates to a lead ion adsorbent, which comprises sodium alginate/modified graphene beads, wherein the preparation method of the modified graphene comprises the following steps: dispersing graphene oxide in deionized water to obtain a graphene oxide suspension, adding phosphatidylserine, and reacting in the presence of EDC and DMAP to obtain the modified graphene. The preparation method of the lead ion adsorbent comprises the steps of dispersing modified graphene and sodium alginate in deionized water, stirring until a uniform solution is formed, dropwise adding the mixed solution into a calcium chloride solution, retaining formed microspheres in the calcium chloride solution, filtering, washing with deionized water, and drying to obtain the lead ion adsorbent. The lead ion adsorbent has a large specific surface area and good lead ion adsorption capacity; the lead ion adsorbent can also increase the activity of soil urease and acid phosphatase and improve the soil quality. |
