通过构建三维电极体系(3D-Ti/Pt-SS-AC),以改性活性炭作为颗粒电极,对某黄金冶炼厂产生的含氰废水进行处理。试验结果表明:反应 150 min时,游离氰化物和总氰化合物的去除率分别为 99.9 %和 96.04 %,Cu、Fe和Zn的去除率分别为 98.52 %、99.28 %和 91.04 %。SEM和EDS结果显示,反应后阴极表面存在大量Cu、Fe和 Zn沉积;XRD表征检测到铜氧化物和 Fe的特征衍射峰;XPS分析观察到 Zn 2p3/2和 Zn 2p1/2轨道的特征峰,证实了金属的有效沉积。FTIR分析显示,反应后颗粒电极表面含氧官能团比反应前减少,证明含氧官能团参与了反应过程,起到提供活性位点、增强催化性能的作用。研究证实了三维电极体系去除氰化物和重金属的可行性,为含氰废水的绿色净化治理提供了新的思路和研究方法。
A 3D electrode system(3D-Ti/Pt-SS-AC)was constructed using modified activated carbon as particleelectrodes to treat cyanide⁃containing wastewater generated by a gold smelting plant. The experimental results showedthat after 150 min of reaction, the removal rates of free cyanide and total cyanide compounds reached 99.9 % and96.04 %, respectively, while the removal rates of Cu, Fe, and Zn were 98.52 %, 99.28 %, and 91.04 %, respectively.SEM and EDS analyses revealed significant deposition of Cu, Fe, and Zn on the cathode surface after the reaction. XRDcharacterization detected characteristic diffraction peaks of Cu oxides and Fe, while XPS analysis observed characteristicpeaks of Zn 2p3/2 and Zn 2p1/2 orbitals, confirming effective metal deposition. FTIR analysis showed a decrease inoxygen⁃containing functional groups on the particle electrode surface after the reaction compared with before, indicatingthat these functional groups participated in the reaction process by providing active sites and enhancing catalyticperformance. This study confirms the feasibility of the 3D electrode system for the removal of cyanide and heavy metals,providing a new approach and research method for the green purification and treatment of cyanide⁃containing wastewater.
