▎ 摘　　要

NOVELTY - The method involves putting rare earth element to be detected in inert container, adding deionized water to prepare into solution, adjusting pH value of solution to 2-7. Graphene oxide or reducing graphene oxide are added in prepared solution, stirring and reinforcing mixed contact of rare earth ion and graphene oxide. A composite solid phase substance of graphene oxide-rare earth is obtained after performing liquid-solid separation to the solution. Luminous phenomenon is generated by the composite substance to judge type and concentration of the rare earth element. USE - Method for enriching and detecting rare earth element by using graphene oxide. ADVANTAGE - The method enables detecting the rare earth element in a simple and convenient manner. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation of a Method for enriching and detecting rare earth element by using graphene oxide.
