▎ 摘　　要

NOVELTY - Preparing graphene/hydroxyapatite aerogel comprises adding GO solution in hydrothermal reaction, adding HA slurry to GO solution, adding distilled water to dilute, fully stirring, reacting at 180 degrees C for 2 hours, naturally cooling to room temperature, taking out the hydrogel product, absorbing water on surface of hydrogel, freezing, and finally freeze-drying to obtain RGO/HA aerogel. USE - The method is useful for preparing graphene/hydroxyapatite aerogel. ADVANTAGE - The graphene/hydroxyapatite aerogel: has more functional groups due to addition of HA, larger specific surface area, better adsorption performance and high recovery rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the graphene/hydroxyapatite aerogel is prepared by above mentioned method.
