▎ 摘  要

NOVELTY - Preparing doped graphene hydrogel comprises (i) adding the graphene into the distilled water to stir and dispersing, the ratio of the graphene and the distilled water is 2:1, the amount of the graphene water solution is 500 ml, (ii) adding the doping agent into the dispersed graphene, stirring, the dropping speed of the doping agent is 25-30 ml/minutes, and the dropping time is 8-12 minutes, (iii) stirring at a certain temperature, initially forming graphene-doped hydrogel, and (iv) filtering. USE - The method is useful for preparing doped graphene hydrogel. ADVANTAGE - The method can effectively remove ions in sewage. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for doped graphene hydrogel, the graphene solution is doped with silver sulfide quantum dot stock solution to generate a graphene hydrogel containing silver sulfide quantum dots, and the generated graphene hydrogel has the function of effectively removing ions in sewage.
