摘要

研究了吲哚美辛在改性多壁碳纳米管(MWCNTs)阴极上的电催化氧化反应。实验探讨了初始浓度、电解电压、pH、电解液浓度和电解时间对吲哚美辛去除率的影响。结果表明，当吲哚美辛浓度为40 mg·L−1，电解电压为30V, pH为11,Na2SO4浓度为2000 mg·L−1，反应时间为1h时，Pt/MWCNTs电极的去除率可达78%。在此条件下，吲哚美辛的降解符合一级动力学。

Electrocatalytic oxidation of indomethacin on a modified carbon nanotube electrode

Electrocatalytic oxidation of indomethacin on a modified multiplewalled carbon nanotubes (MWCNTs) cathode in aqueous solution was studied in this paper. The experiments were carried out to explore the effects of initial concentration, electrolytic voltage, pH, concentration of electrolyte and electrolysis time on removal rate of indomethacin. The results of show that the removal rate reached 78% by using the Pt/MWCNTs electrode, when the concentration of indomethacin was 40 mg·L−1, the electrolytic voltage was 30V, the pH was 11, the concentration of Na2SO4 was 2000 mg·L−1 and the reaction time was 1h. Under such conditions, indomethacin degradation accords with the first order kinetics.
