Abstract: The present invention provides a zirconium-based metal-organic framework material and a preparation method therefor and the use thereof, and an adsorption separation device and method. The zirconium-based metal-organic framework material has a chemical structural formula of [C18H6O16Zr3]n, and comprises zirconium and an organic ligand forming a coordination bond with zirconium, wherein the organic ligand is diphenylethyne-3,3′,5,5′-tetracarboxylic acid. The molecular structure of the zirconium-based metal-organic framework material of the present invention is a three-position network structure having a one-dimensional channel; and in the present invention, the size of the one-dimensional channel is accurately controlled by changing the aspect ratio of the organic ligand, such that the zirconium-based metal-organic framework material efficiently separates a hexane isomer by means of a kinetic effect.
