摘要
背景面对不断升级的水污染挑战,本研究探索了使用 NiTiO3 包晶石改性阴极进行电-芬顿(EF)处理以去除废水中亚甲基蓝(MB)的功效。方法采用中央复合设计(CCD)方法,对影响 EF 过程的重要因素(包括 MB 初始浓度、pH 值、应用电流和反应时间)进行了优化。研究结果电化学分析表明,与裸石墨电极相比,NiTiO3/石墨电极性能优越,突出表现在增加了电活性位点、增强了氧还原能力、降低了电荷转移电阻。在最佳条件下(初始浓度:25 毫克/升;pH 值:4.5;电流:40 毫安;时间:110 分钟),对 EF 过程进行了微调,甲基溴的去除率达到 95.38%。这项研究强调了 NiTiO3 改性阴极在先进水处理应用中的巨大潜力,突出了它们在对抗持久性有机污染物方面的强大效率和环境意义。
NiTiO3 nanoparticles: An environmental game changer in electro-Fenton wastewater remediation
Background
In the face of escalating water pollution challenges, the study explores the efficacy of Electro-Fenton (EF) treatment using NiTiO3 perovskite-modified cathodes for methylene blue (MB) removal from wastewater.
Methods
Employing a Central Composite Design (CCD) methodology, significant factors influencing the EF process, including initial MB concentration, pH, applied current, and reaction time, were optimized. The NiTiO3 catalyst was meticulously characterized, revealing its rhombohedral crystal structure, uniform particle distribution, and efficient charge transfer properties.
Findings
Electrochemical analyses demonstrated the superior performance of the NiTiO3/Graphite electrode, emphasizing its increased electroactive sites, enhanced oxygen reduction capability, and reduced charge transfer resistance compared to the bare Graphite electrode. The EF process was finely tuned, demonstrating a 95.38 % removal efficiency of MB at optimal conditions (initial concentration: 25 mg L−1, pH: 4.5, current: 40 mA, time: 110 min). This study underscores the promising potential of NiTiO3-modified cathodes in advanced water treatment applications, highlighting their robust efficiency and environmental significance in combating persistent organic pollutants.
