Abstract

The invention relates to the technical field of wastewater adsorption materials, in particular to a method for preparing an airgel-like environmental functional material with a green solvent and its application, which includes step 1, obtaining corn pith; step 2, mixing choline chloride and organic carboxylic acid , heating, choline chloride and organic carboxylic acid are melted completely, cooling, add distilled water, and stir evenly, make mixed solution; Step 3, add corn pith to mixed solution and carry out sufficient reaction, fully react corn pith after completion of reaction Wash until neutral, freeze and dry; step 4, mix sodium phosphate solution, tetramethylpiperidine oxide and sodium chlorite to form a mixed solution, add sodium hypochlorite and sodium phosphate mixed solution to the mixed solution, add corn After overnight, the solution was reacted under the shaker, and finally the corn pith was washed, frozen and dried. The prepared environmental functional material has a good adsorption effect on oil substances, dye ions and the like in waste water.

Description

technical field

[0001] The invention relates to the technical field of wastewater adsorption materials, in particular to a method for preparing an airgel-like environmental functional material with a green solvent and its application. Background technique

[0002] Industrial wastewater (industrial wastewater) includes production wastewater, production sewage and cooling water. pollutants. There are many kinds of industrial wastewater with complex components. The wastewater may contain oil, heavy metal ions, ionic dyes, etc. Direct discharge will cause serious pollution to rivers, lakes and soil. The existing technology generally needs to treat the wastewater before discharging it. Purification treatment, the use of adsorbents to adsorb pollutants in wastewater is a common method in wastewater purification treatment, but the existing adsorbent preparation process is complex, cumbersome, time-consuming, low production efficiency, and the powder is not granular. It is good fo...
