Furfural removal by electrochemically activated peroxydisulfate (E-PS) and peroxymonosulfate (E-PMS) was investigated. The effect of different anodes was investigated for the electrochemical activation of oxidants. Box Behnken Design was applied to determine optimum operating conditions, which were determined as follows; PS concentration: 2.3 mM, applied current: 1.15 A, pH: 3.5, and reaction time: 118.3 min for E-PS process; PMS concentration: 1.8 mM, applied current: 1.05 A, pH: 3.3, and reaction time: 107.8 min for E-PMS process. The results of the study showed that the E-PMS process is more advantageous in terms of the chemical and electricity costs to be used.
研究了通过电化学活化过二硫酸盐（E-PS）和过一硫酸盐（E-PMS）去除糠醛的方法。研究了不同阳极对氧化剂电化学活化的影响。采用Box Behnken设计确定最佳操作条件，具体如下：E-PS工艺中，PS浓度：2.3 mM，施加电流：1.15 A，pH：3.5，反应时间：118.3分钟；E-PMS工艺中，PMS浓度：1.8 mM，施加电流：1.05 A，pH：3.3，反应时间：107.8分钟。研究结果表明，就使用的化学成本和电力成本而言，E-PMS工艺更具优势。
