摘要

本研究旨在评价CuFe12O19/ cu /氙体系对四环素水溶液的降解性能。本研究利用青蒿提取物绿色合成纳米复合材料后,通过XRD、FTIR、FESEM、TEM、BET、XPS、DRS、DLS、EDS、VSM、PL等手段对其进行了表征,并对影响四环素光催化降解的时间、pH、TC初始浓度、纳米复合材料剂量等参数进行了评价。结果表明,随着pH和催化剂用量的增加,降解效率提高。在最佳条件下(pH = 9,纳米复合材料剂量为0.5 g/L,时间为200 min),浓度为20 mg/L的工艺效率为100%。四环素降解动力学符合准一阶方程。此外,结果表明,经过连续6次循环后,合成的催化剂的性能没有明显降低。矿化试验结果表明,在最佳反应条件下,浓度为20 mg/L的四环素合成溶液的COD和TOC的降解率分别达到87.25%和73.06%。清除剂实验证实OH在四环素的分解过程中起着最关键的作用。一般来说,CuFe12O19/ cu /氙光催化体系可以有效地降解水中环境中的四环素。

Construction of S-scheme CuFe12O19/CuS green nanocomposite for effective photocatalytic degradation of tetracycline from aqueous solution: mechanism, recyclability, and kinetic study

This research was designed to evaluate the performance of the CuFe12O19/CuS/Xenon system in the degradation of tetracycline in aqueous solutions. In this study, after green synthesis of nanocomposite using the extract of the Artemisia plant, its properties were determined by XRD, FTIR, FESEM, TEM, BET, XPS, DRS, DLS, EDS, VSM, and PL. In addition, parameters affecting the photocatalytic degradation of tetracycline, including time, pH, TC initial concentration, and nanocomposite dose, were assessed. The findings showed that the degradation efficiency increases with increasing pH and catalyst dosage. Under optimum circumstances (pH = 9, nanocomposite dose of 0.5 g/L, and time 200 min), the process efficiency with concentration of 20 mg/L was 100%. The kinetics of the degradation rate of tetracycline obeyed the pseudo-first-order equation. In addition, the results show that after six consecutive cycles, the synthesized catalyst’s ability did not significantly reduce. The results of the mineralization tests revealed that the COD and TOC degradation of the synthetic solution of tetracycline with a concentration of 20 mg/L reached 87.25% and 73.06%, respectively, in the optimal reaction conditions. The scavenger experiments confirmed that OH plays the most crucial role in the decomposition process of tetracycline. Generally, the CuFe12O19/CuS/Xenon photocatalytic system can effectively degradation tetracycline from aqueous environments.
