Zn/Ni-MOF衍生碳的制备及其活化过硫酸盐性能研究

Preparation of Zn/Ni-MOFs-derived carbon and its activated persulfate properties

四环素类抗生素(TCs)是一类应用非常广泛的广谱抗菌药物,但因其高溶解性且易于积累,对水环境和人类健康造成危害。通过过氧单硫酸盐(PMS)活化在反应体系中产生高氧化电位的去氧化有机物,是降解此类抗生素废水的有效途径。通过水热法和高温煅烧法制备了Zn/Ni-MOF衍生碳(Zn/Ni-MOFs-PC)材料,催化过硫酸盐降解水中盐酸四环素。研究结果表明,碳化之后介孔含量增加丰富了孔道结构,带来更宽离子传输通道的同时可产生更多的活性位点,优化催化条件对盐酸四环素呈现良好的催化活性,同时拥有优异的循环稳定性。

Tetracycline antibiotics(TCs)are a class of broad-spectrum antimicrobials with wide range of applications.However they posed a hazard to the water environment and human health due to their high solubility in the environment and easy accumulation.Deoxidized organic matter with high oxidation potential in the reaction system by way of peroxymonosulfate(PMS)activation is an effective way to degrade such anti-biotic wastewater.Zn/Ni-MOFs-PC materials were prepared by hydrothermal method and high temperature calcination and they applied to catalyze the degradation of tetracycline hydrochloride in water by persulfate.The results showed that the increase of mesoporous content after carbonization enriched the pore structure,brought wider ion transport channels and produced more active sites.The optimized catalytic conditions showed good catalytic activity for tetracycline hydrochloride with excellent cycle stability.
