| 摘 要： | 对以空气扩散电极为阴极,泡沫镍为阳极的电化学体系降解苯酚模拟废水进行了研究.采用分光光度法测定苯酚浓度,研究了电解时间﹑电流密度﹑苯酚初始浓度对苯酚去除率的影响.结果表明,空气扩散电极/泡沫镍电化学体系对含酚废水有很强的降解能力,初始浓度为200mg/L的苯酚溶液,在电流密度30mA/cm2条件下电解180min,苯酚去除率99.3%,化学需氧量(COD)去除率80%.

| Abstract: | Simulated wastewater of phenol was electrolyzed by electrochemical system including air diffuse electrode (ADE) as cathode and foam nickel as anode in this paper. Phenol concentration was measured by spectrophotometric method and the influence of factors such as electrolysis time, current density, initial phenol concentration on phenol re- movalrate was studied. The result showed that ADE/foam nickel electrochemicalsystem has strong degradation capacity. When initial phenol concentration was 200 mg/L and current density was 30 mA/cm 2 , the phenol removal rate reached 99.3% and chemical oxygen demand (COD) removal rate reached 80% after electrolyzing for 180 min. |
