Preparation and evaluation of Zn2(BDC)2(DABCO) MOF-hydroxyapatite nanocomposite to remove tetracycline from aqueous solution |
|
| چکیده انگلیسی مقاله |
Objective(s): In recent years, porous materials have shown good potential for adsorption due to their high surface area. Among them, hydroxyapatite (HA) is important as an inorganic material. While metal-organic frameworks (MOFs) have attracted much attention as hybrid materials consisting of organic and inorganic compounds with special properties
Methods: In this study, Zn2(BDC)2(DABCO) MOF-HA nanocomposite (NC) was prepared by solvothermal method with precursors that are: Zn = zinc acetate dehydrates, BDC = 1,4-benzenedicarboxylate, and DABCO = 1,4-diazabicyclo [2.2.2] octane. This nanostructure was used to remove tetracycline drug from aqueous solution. Samples were characterized by Fourier Transform InfraRed (FTIR) spectroscopy to evaluate functional groups, X-Ray diffraction (XRD) analysis of crystal structure, field emission scanning electron microscope (FESEM) to determine morphology and size, BET analysis for measurement of surface area, and Ultraviolet–Visible (UV–Vis) spectroscopy to study drug adsorption. The effect of some important parameters on removal efficiency, such as drug concentration, nanocomposite amount, removal time and solution pH were studied. In order to reach best removal condition, the effect of the parameters and their interactions was optimized using the Box-Behnken Design (BBD) and the response surface methodology.
Results: The synthesis of Zn2(BDC)2(DABCO) MOF-hydroxyapatite nanocomposite was confirmed using identification methods. The functional groups, crystal structure and surface area were evaluated by FTIR, XRD and BET respectively. The nanoscale size was approved by FESEM. In the optimum condition, the removal efficiency more than 98% was obtained.
Conclusions: According to the results, MOF and its nanocomposite can be a good choice for tetracycline removal and have good potential for the development of different adsorbents. |
