▎ 摘　　要

NOVELTY - Aerogel material comprises 29-31 pts. wt. aqueous dispersion of graphene oxide, 0.10-0.15 pts. wt. aqueous solution of hydrazine hydrate. The mass fraction of the aqueous solution of hydrazine hydrate is 0-50 wt.%. The concentration of the graphene oxide aqueous dispersion is 3-5mg/mL. USE - Aerogel material. ADVANTAGE - The aerogel material has stability, high efficiency, low cost, non-toxicity, solves problem that the existing activated persulfate oxidation method uses powdered carbon material as catalyst, and avoids secondary pollution to the environment. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing aerogel material, which involves weighing aqueous dispersion of graphene oxide and aqueous solution of hydrazine hydrate, keeping at 190-210 degrees C for 2-4 hours, and cooling to room temperature to obtain hydrogel, dialyzing hydrogel to obtain dialyzed hydrogel and freeze-drying dialyzed hydrogel; (2) a catalyst, which comprises aerogel material; and (3) a method for degrading sulfonamides wastewater, which involves mixing sulfonamide-based pharmaceutical wastewater to be degraded with catalyst, and then adding persulfate to aerate.
