This work investigates the electrochemical oxidation of palm oil mill effluent (POME) treatment using platinum (Pt) as anode and graphite as a cathode. The response surface methodology was used to investigate the relationships between different factors conditions (voltage, electrolysis time and chemical support) and responses of the treatment (chemical oxygen demand reduction, colour removal, and total oil removal). A quadratic mathematical model was chosen for all responses using Box-Behnken Design (BBD) with R 0.9853 for COD reduction, R 0.9478 for colour removal and R 0.9185 for total oil removal. According to Derringer's function desirability, under the optimum condition (Voltage 15, electrolysis time 2 h, and 19.95 mg/L NaCl) of POME treatment, 84% of COD reduction, 98% of colour removal and 99% total oil of removal could be achieved. These results indicate that platinum as an anode material is effective for the electrochemical oxidation treatment of POME.
本工作研究了使用铂（Pt）作为阳极和石墨作为阴极的电化学氧化处理棕榈油厂废水（POME）。响应面法用于研究不同因素条件（电压、电解时间和化学支持）与处理的反应（化学需氧量降低、颜色去除和总油去除）之间的关系。使用 Box-Behnken 设计（BBD）选择了所有响应的二次数学模型，COD 降低的 R 0.9853，颜色去除的 R 0.9478，总油去除的 R 0.9185。根据 Derringer 的函数理想性，在 POME 处理的最佳条件（电压 15、电解时间 2 小时和 19.95 mg/L NaCl）下，COD 降低 84%，颜色去除 98%，总油去除 99%。这些结果表明，铂作为阳极材料对于 POME 的电化学氧化处理是有效的。
