| 摘 要： | 采用溶胶-凝胶法制备泡沫镍负载TiO2电极,并用场发射扫描电子显微镜和XRD仪对其表面形貌、颗粒大小和晶体结构进行表征.以紫外灯为光源,负载TiO2的泡沫镍电极为阳极,Pt电极为阴极,建立光电催化体系,对废水中的农药敌百虫进行降解.当采用浓度0.02 mol/L的NaCl溶液为电解质溶液、初始废水pH为6.0、电流密度为2.5 mA/cm2、降解时间为120 min时进行光电催化反应,模拟敌百虫废水COD的去除率达到81.8％.

| Abstract: | The foamed nickel electrode loaded with TiO2 film was prepared by sol-gel method,and was characterized by field emission scan electron microscopy(FESEM) and XRD.The photoelectricatalytic system for degradation of dipterex in wastewater was set up by using UV lamp as light source,TiO2-loaded foamed nickel electrode as anode,platinum electrode as cathode.When the NaCl solution with 0.02 mol/L of concentration is used as the electrolyte solution,the initial wastewater pH is 6.0,the current density is 2.5 mA/cm2,the degradation time is 120 min,the COD removal rate of the dipterex wastewater is 81.8%. |
