Use of Combined Electrochemical Approaches for Mineralization and Detection of Hydroquinone Using PbO2 Electrodes
The electrochemical oxidation (EO) of hydroquinone (H2Q)has been performed, in acidic media, at PbO2 electrode by galvanostaticelectrolysis applying 10 and 30 mAcm−2. The concentration ofH2Q during its EO was also monitored by differential pulse voltammetry(DPV) by using PbO2 electrode. The experime...

| Sumario: | The electrochemical oxidation (EO) of hydroquinone (H2Q)has been performed, in acidic media, at PbO2 electrode by galvanostaticelectrolysis applying 10 and 30 mAcm−2. The concentration ofH2Q during its EO was also monitored by differential pulse voltammetry(DPV) by using PbO2 electrode. The experimental results ofgalvanostatic electrolyses showed that the performances of the processremarkably depend on the applied current density and in particular,the removal efficiencies obtained at PbO2 anode were 100% and 80%,at 30 and 10 mAcm−2, respectively. Additionally, the electroanalyticaltechnique was efficiently used as a detection method during H2Qelectrooxidation and when DPV analyses were compared with HPLCmethod, it achieved a good fit, confidence intervals and limits. |
