NOVELTY - Preparation of graphene/carrageenan aerogel comprises mixing graphene oxide solution and carrageenan solution, stirring, adding vitamin C, ultrasonically dispersing, putting into mold, sealing, and molding to 85-90 degrees C for 1-3 hours to obtain hydrogel; and soaking to calcium chloride solution to carry out crosslinking reaction for 20-60 minutes, repeatedly soaking and washing, and freeze-drying. USE - The method is for preparation of graphene/carrageenan aerogel used for removing organic dyes from printing and dyeing wastewater (claimed). ADVANTAGE - The aerogel has good adsorption effect on neutral red and methylene blue organic dyes, removal rate of above 90%, fast adsorption rate, and good stability.
