| titleOfInvention | Preparation method and application of composite sponge adsorbent for rapidly adsorbing mercury ions |
| abstract | The invention relates to a preparation method and application of a composite sponge adsorbent for quickly and efficiently adsorbing mercury ions in an aqueous solution. The method adopts cheap and easily-obtained cellulose, lignin or wheat protein powder as a matrix raw material, obtains a suspension by high-speed dispersion of the matrix raw material, adds different amounts of chitosan, chitin and polyvinyl alcohol or polyethylene glycol, and prepares the composite sponge adsorbent by a simple cross-linking and freeze-drying combination method. The whole preparation process is carried out in aqueous solution, the process is simple and easy to operate, special process equipment is not needed, and the cost is low. The sponge adsorbing material prepared by the method is high in adsorption rate, high in selective adsorption capacity on mercury ions, less affected by pH value, recyclable and environment-friendly. Has good application prospect in the actual heavy metal wastewater treatment. |
