▎ 摘  要

NOVELTY - Cesium ion adsorbent comprises graphene oxide complex having hydrophilic group of metal carboxylate (I). USE - The cesium ion adsorbent is useful for removing cesium ions. ADVANTAGE - The adsorbent is capable of efficiently removing cesium even at low initial concentration. DETAILED DESCRIPTION - Cesium ion adsorbent comprises graphene oxide complex having hydrophilic group of metal carboxylate (COO-M+) (I). M = H, Li, Na, K, Rb or quaternary amine. INDEPENDENT CLAIMS are also included for: (1) method for manufacturing cesium ion adsorbent, comprising synthesizing graphene oxide and synthesizing graphene oxide complex by wet spinning of graphene oxide with solution containing salt (M+OH-) (II); and (2) method for removing cesium ions, comprising utilizing cesium ion adsorbent to remove cesium ions.
