The invention relates to a metal-organic framework adsorbent, a one-step preparation method and application thereof, and belongs to the technical field of material preparation. Completely mix 2.2-dithiodibenzoic acid and zirconium tetrachloride in DMF and hydrochloric acid to obtain a mixture; transfer the mixture to a three-necked flask and heat on an oil bath at 130°C for 24 hours; remove the solid material with After washing with water ethanol, centrifugation, and vacuum drying, the obtained metal-organic framework adsorbent was labeled as DTDD-MOF. The invention draws on the success of metal-organic framework materials (MOFs) in the field of adsorption, according to the hard-soft acid-base (HSAB) theory, and uses 2,2'-dithiodibenzoic acid as an organic ligand to prepare a novel MOF by a one-step method Absorbent for efficient and selective adsorption of Au(III) from industrial wastewater. The method is simple and clear, the material cost is low, the process preparation is simple, the adsorbent can be reused, and has a good application prospect. |
