Preparation of a Novel Resin-Based Metal Organic Skeleton and Its Adsorption Performance on Sodium Aloxacillin in Water
In this study,a composite adsorbent D201@UIO-66 was prepared by synthesizing UIO-66 within a polystyrene anion exchanger D201 and used to remove pharmaceutical con-tamination from water bodies.This approach improved the structural stability of the metal-organic backbone in the liquid and improved the adsorption performance.The composite ad-sorbent was characterized by XRD,SEM,EDS,FT-IR and BET,and the results showed that UIO-66 was successfully loaded in D201.The batch adsorption experiments showed that the maximum experimental adsorption capacity of the composite adsorbent was 142.5 mg·g-1 when the amount of composite adsorbent was 0.5 g·L-1.The composite adsor-bent exhibited adsorption stability over a wide pH range.The composite adsorbent showed selective adsorption of sodium aloxacillin in the presence of other anions.The adsorption ki-netics were consistent with the pseudo-secondary kinetic adsorption model,and the adsorp-tion isotherms were more consistent with the Langmuir model.The composite adsorbent D201@UIO-66 has good potential for the adsorption of pharmaceutical contamination in water.
