摘要

本研究探讨了使用通过超声辅助电化学沉积制备的 PbO₂涂层石墨（G-PbO₂）电极对厨房废水（KW）进行电化学处理的问题。通过各种技术，包括 X 射线衍射分析 (XRD)、X 射线光电子能谱 (XPS)、循环伏安法 (CV)、电化学阻抗能谱 (EIS) 和扫描电子显微镜 (SEM)，对 G-PbO2 电极进行了表征，证实了 PbO₂ 的成功沉积和催化活性的增强。在最佳条件下（电流密度 0.75 Adm-2、电解质浓度 1.5 gL-1、电极间距 2 cm、pH 值 3），G-PbO₂ 电极的 COD 减排率达到 94%，能耗为 0.002 kWh gCOD-1。这些结果凸显了该电极在去除 COD 方面的优越性能和低能耗。

Improved kitchen wastewater treatment using PbO2-coated graphite electrode

This study investigates the electrochemical treatment of kitchen wastewater (KW) using a PbO₂-coated graphite (G-PbO₂) electrode prepared via ultrasound-assisted electrochemical deposition. The G-PbO₂ electrode was characterised through various techniques, including X-ray diffraction analysis (XRD), X-ray photoelectron spectroscopy (XPS), cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and scanning electron microscopy (SEM), confirming the successful deposition of PbO₂ and enhanced catalytic activity. Under optimal conditions (current density 0.75 Adm⁻², electrolyte concentration 1.5 gL^-1, electrode distance 2 cm, and pH 3), the G-PbO₂ electrode achieved a 94 % COD reduction with an energy consumption of 0.002 kWh gCOD⁻¹. These results highlight the superior performance of the electrode in COD removal, accompanied by low energy consumption.
