1. A method for separating mixed xylenes, comprising subjecting the mixed xylenes to adsorptive separation by an adsorbent containing a metal-organic framework material to separate one or more xylene isomers from the mixed xylenes,
wherein the metal-organic framework material comprises metal ions and an organic ligand, and wherein the organic ligand comprises 2,5-dihydroxy-1,4-benzoquinone.
