| description | The present disclosure provides a method for enriching and purifying heavy metals in seawater, which belongs to the technical field of seawater purification. The method specifically includes the following steps: taking Microcyslis aeruginosa as a raw material, extracting acidic polysaccharide from the Microcyslis aeruginosa, conducting esterification cross-linking between the acidic polysaccharide and 2- formylaminosorbitol to obtain a hydrogel with a cross-linking network structure, modifying the hydrogel with sulfamonomethoxine to obtain a modified Microcyslis aeruginosa polysaccharide hydrogel, mixing the hydrogel with diatomite, zeolite, trigonelline, and disodium epoxysuccinate to prepare an adsorbent with a high adsorption capacity, and putting the adsorbent into polluted seawater to adsorb heavy metal ions. The method has an excellent heavy metal removal effect, can rapidly remove heavy metal ions without causing secondary pollution, and has great application prospects. |
