| titleOfInvention | Preparation method and application of three-dimensional porous algae-based/chitosan aerogel for uranium-containing wastewater treatment |
| abstract | The invention relates to a preparation method of three-dimensional porous algae-based/chitosan aerogel and application of the three-dimensional porous algae-based/chitosan aerogel in treatment of uranium-containing wastewater. A preparation method of a three-dimensional porous algae-based/chitosan aerogel for uranium-containing wastewater treatment comprises the steps of taking chitosan and chlorella pyrenoidosa as base materials, utilizing ammonium bicarbonate or sodium bicarbonate to foam in the aerogel to form holes, and then carrying out low-temperature freezing and solvent replacement to prepare the three-dimensional porous algae-based/chitosan aerogel. The three-dimensional porous algae-based/chitosan aerogel prepared by the invention has the advantages of large specific surface area, controllable volume, easy separation from a solution and good mechanical strength. The adsorption saturation capacity of the three-dimensional porous algae-based/chitosan aerogel on uranium reaches 575mg/g, the removal rate of uranium below 100mg/L reaches more than 95%, and the three-dimensional porous algae-based/chitosan aerogel can be applied to enrichment and uranium removal in aqueous solution. |
