▎ 摘  要

NOVELTY - Phosphonic acid functionalized polymer/graphene nanoribbon composite aerogel, is claimed. The composite aerogel is based on graphene oxide nanoribbons. A polymer aerogel with phosphonic acid groups as functional groups is grafted onto the substrate. USE - The aerogel is useful as adsorbent for treating thorium-containing wastewater (claimed) and field of nuclear wastewater treatment. ADVANTAGE - The aerogel has adsorption capacity of 300-380 mg/g. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for method for treating thorium-containing wastewater using phosphonic acid functionalized polymer/graphene nanoribbon composite aerogel, comprising adjusting the pH value of the thorium-containing wastewater to be treated to 1-4, then adding phosphonic acid functionalized polymer/graphene nanoribbon composite aerogel under the condition of temperature of 5-45 degrees C, vibrating and adsorbing for 0.5-2 hours, then taking out the phosphonic acid functionalized polymer/graphene nanoribbon composite aerogel, and completing the treatment of thorium-containing wastewater.
