▎ 摘  要

NOVELTY - Preparing functional air gel, comprises (a) subjecting graphite in to sonication, forming a uniform oxide graphene dispersion; (b) adding a complex compound having a heavy metal complex in an oxidized graphene dispersion, and stirring to form a homogeneous mixed solution; (c) subjecting the mixed solution into a heating reaction, to obtain a functionalized hydrogel modified by meridian complex; and (d) replacing solvent by a functionalized hydrogel, and then drying, to obtain a functionalized aerogels. USE - The method is useful for preparing functional air gel (claimed). ADVANTAGE - The air gel has heavy metal ion adsorption and desorption capability; utilizes the air gel high porosity, large specific surface area, low density; and improves the content of the heavy metal in the waste water.
