▎ 摘　　要

NOVELTY - Preparing graphene oxide functionalized metal organic framework (UiO-66-NH2) comprises (i) pouring the graphene oxide into the reaction kettle, and adding N,N dimethylformamide, shaking and mixing, mixed solution, (ii) adding zirconium tetrachloride and 2-amino-1,4-phthalic acid into the mixed solution, shaking and mixing, placing in a hydrothermal reaction kettle for hydrothermal synthesis, (iii) cooling the product to room temperature, washing with N,N-dimethylformamide and absolute ethanol many times respectively, placing in a centrifuge for centrifugation to obtain an off-white powder, and (iv) rinsing off-white powder with absolute ethanol again, and drying once and adding in a vacuum oven for secondary drying. USE - The graphene oxide functionalized UiO-66-NH2 is useful for measuring concentration of gallium ions (claimed). ADVANTAGE - The adsorption rate of graphene oxide functionalized UiO66NH2 to gallium ions can reach more than 95%, and after repeated use, the adsorption rate of graphene oxide functionalized UiO66NH2 to gallium ions can still be maintained at more than 80%, and the cycle performance is high. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for used method of graphene oxide functionalized UiO-66-NH2, comprising mixing graphene oxide functionalized UiO-66-NH2 with the gallium solution and shaken, after the adsorption is balanced, measuring concentration of gallium ions in the solution after adsorption, and eluting with an eluent.. DESCRIPTION OF DRAWING(S) - The drawing shows a process flow chart of graphene oxide functionalized UiO66NH2.
