The presence of antibiotics in the aquatic environment can cause significant environmental and human health problems even at trace concentrations. Conventional treatment systems alone are ineffective in removing these resistant antibiotics. To address this problem, oxidation and adsorption techniques were used to explore the removal of recalcitrant antibiotic chloramphenicol (CAP). An aluminum-based metal-organic framework (AlMIL) with high surface area and extended porosity, was prepared and used both as adsorbent and catalyst for the oxidation of CAP. Characterization of the Al-MIL revealed a large surface area of 1137 m2 g− 1 , a homogeneous microporous structure, good crystallinity, and particle size in the range of 200–400 nm. Adsorption of CAP on AlMIL achieved equilibrium afte...

One of the attractive iron-based metal organic framework (MOF) MIL-101(Fe) (Material Institute Lavoisier, MIL) and amine-functionalized NH2-MIL-101(Fe) materials were synthesized by conventional solvothermal method and characterized by TGA (Thermo Gravimetric Analysis), SEM (Scanning Electron Microscopy), XRD (X-Ray Diffractograms), BET (Braunner Emmet Teller) and FTIR (Fourier Transform Infrared Spectroscopy). Characterization results indicated that MIL101(Fe) materials have well defined morphology, good thermal stability, high surface area and also high porosity. These MOF materials were used as photocatalysts for photodegradation of a pesticide, imidacloprid (IMC). The response surface methodology (RSM) was applied in designing the IMC photodegradation experiments for evaluating the...
