Synthesis and characterization of Copper Metal-Organic Frameworks for adsorption of Phenol

The sucess of the Metal-Organic Frameworks (MOFs) has stimulated studies to verify the removal by adsorption of different environmental contaminants. Phenol is a highly toxic aromatic hydrocarbon deemed as a contaminant in both soil and water. The objective of this work is to make a contribution to the development of new MOFs and use them as adsorbent for the contaminant phenol. Synthesis, characterization and evaluation of the adsorption of phenol in compounds of Copper containing carboxylates derived from Trimesic acid (BTC) and p-Fenilenediacetic acid (p-Fen) and 4,4’ Bipyridine (Bpy) are described. The IR spectra of the two compounds obtainded didn’t showed strong bands arond 1700cm-1 wich are characteristic of the C=O stretching of the COOH group, but bands are observed assigned to asymmetric and symetric stretching of the COO- group, indicating the coordination of the carboxylate to the metallic center. The spectra also showed a band at 1600 cm-1 that has been defined on the literature as N=C stretching of compouds of Copper with Bpy. The FT-IR spectra of Cu(BTCBpy) after interaction with Phenol showed a band around 3500cm-1 and a large one proceeding it that are characteristic of the O-H stretching absorption of phenol. IR spectra showed satisfactory results for MOFs containg mixed linkers and indicates possible adsorption of Phenol. Further Uv-vis sperctroscopy and HPLC studies wil be performed to truly confirm the adsorption.
