▎ 摘　　要

NOVELTY - Aerogels including reduced graphene oxide (RGO), metal ferrocyanide nanoparticles (MFNP), and water-soluble polymers (WP) are produced by irradiating radiation to a mixture of water-soluble polymers, graphene oxide, and ferrocyanide metal nanoparticle precursor. USE - Preparation of aerogels for adsorbent used for removing radioactive cesium and/or radioactive strontium, and for removing organic dyes and/or organic solvents (all claimed). ADVANTAGE - The RGO/MFNP/WP aerogel has excellent adsorption ability for organic pollutants, such as organic dyes and/or organic dyes, in a simplified method, and excellent adsorption ability for radionuclides, such as cesium and strontium, by controlling the floating ability of the RGO/MFNP/WP aerogel. Since the RGO/MFNP/WP aerogel exhibits an ultra-low density, it is easy to recover the aerogel used for adsorption, and the reusability can be excellent by separating the adsorbed material from the recovered aerogel. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for RGO/MFNP/WP aerogel.
