Rapid Room-temperature Synthesis and Tetracycline Adsorption of Novel Ga-based Metal-organic Gels
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.
