▎ 摘　　要

NOVELTY - Preparing boron adsorbent gas gel comprises adding reducing agent, sequentially nano-tube aqueous solution in the aqueous solution graphene then adding meglumine, stirring and dissolving, transferring to hydrothermal, reaction vessel at 90℃ for 8-16 hours, cooling to room temperature to obtain the meglumine/carbon/carbon graphene-tube hydrogel; taking out the hydrogel obtained, washing with water, freezing and drying to obtain gas gel; immersing the aerogel in the epoxy chloropropane liquid, transferring to hydrothermal reaction vessel for 8-16 hours at 100-140℃, cooling to room temperature, opening the kettle, pouring the epoxy chloropropane liquid in the system to transfer, repeatedly soaking the obtained solid by dimethylformamide (DMF), washing until the eluent is colorless, then deionized water, washing to obtain the hydrogel, freezing and drying to obtain the boron adsorbent gas gel. USE - Method for preparing boron adsorbent gas gel, which is used in boron complex reaction in aqueous solution. ADVANTAGE - The method has a reinforced concrete structure, good mechanical property and excellent boron adsorption performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of boron adsorption gas gel in boron complex reaction in aqueous solution where the application is to use the gas to gel and extract boron in the water phase.
