MOF based on cobalt terephthalate and 1,10-phenanthroline was synthesized according to a modified procedure by the interaction of cobalt nitrate, terephthalic acid, and 1,10-phenanthroline in the presence of alkali. MOF has been used to extract the organic Congo red and methylene blue dyes from their aqueous solutions. The degree of removal depends on temperature and reaches values close to 100% within 60 min at 291 and 308 K. The limiting adsorption is 40 mg/g, and the Langmuir model is in good agreement with the experimental results. The antioxidant activity of MOF was evaluated on a model solution of adrenalin hydrochloride in an alkaline medium with a maximum inhibition of the oxidation of the model compound of 87.05%. The antibacterial activity of MOF against Escherichia coli (E. coli) was assessed as satisfactory, which is explained by the release of metal cations and organic ligand, and the long period of action is due to their synergistic action.
