Abstract:

In this research, Ga-based metal-organic gels(Ga-TATB) were synthesized at room temperature through a rapid and simple strategy. Ga-TATB could effectively remove tetracycline(TC) from aqueous solution due to the large specific surface area, unique porous structure and excellent structural stability. The adsorption process of TC by Ga-TATB kept well to the pseudo-second-order kinetic model and the Freundlich isotherm model, and the maximum adsorption capacity could reach 149.92 mg/g at pH=6.00 and 25 ℃. Furthermore, the effect of solution pH, Ga-TATB dosage, ionic strength, coexisting inorganic ions, contact time and TC concentration on the adsorption process was systematically investigated, and the possible mechanism of Ga-TATB adsorption towards TC was proposed based on the experimental results. It is worth noting that the strong anti-interference ability and stable reusability make Ga-TATB a good application prospect in tetracycline antibiotic wastewater remediation.
