The advanced oxidation of paracetamol (PCT), frequently used analgesic, promoted by electro-oxidation (EOX), goethite catalyzed electro-Fenton (GEF) with goethite, ozonation and electro-peroxone (E-peroxone) was investigated. The degradation efficiency of the processes was evaluated considering the decay of PCT versus time. All the processes showed pseudo-first order character for PCT degradation. kobs values, at optimum conditions for an individual process, were defined as 0.0022, 0.0029, 0.0870 and 0.1662 min-1 for EOX, GEF, ozonation and E-peroxone processes, respectively. Where EOX and GEF processes showed poor degradation efficiencies, novel E-peroxone process provided complete removal of PCT. The degradation of the PCT would mostly occur by OH• and molecular O3 due to the higher rate constants achieved at E-peroxone and ozonation. Conversely, with lower kobs values gained at EOX, hydroxyl radicals would not contribute noticeably to the PCT degradation. In GEF process, due to relatively lower OH• production rate, lower kobs values were obtained for the degradation of PCT. The formation of reaction intermediates, aromatics and carboxylic acids, was also determined in this study.

“…NaClO production from electrolysis depends on the performance of anodes . Commonly used electrodes can be divided into non‐metal electrodes (graphite electrodes) and metal electrodes (Ni, Fe, Pt, Pb, Hg, Ti). The Ti electrode is stable in size and has a low working pressure, thus reducing power consumption.…”

The electrochemical preparation of NaClO has been widely used for the production of industrial disinfectant. To reduce the cost of electrode preparation using the brushing method, this paper introduces a method for the electrodeposition for RuO2/Ti and RuO2‐IrO2/Ti preparation and NaCl solution electrolysis. The deposition of Ir improves the uniformity and stability of the RuO2/Ti electrode. The optimum preparation conditions and additive concentrations were investigated in detail through the orthogonal experiment. By adjusting the electroplating time, temperature and voltage, the electrode with a high content of available chlorine was synthesized successfully. The physicochemical properties of the as‐prepared RuO2/Ti and RuO2‐IrO2/Ti were determined by XRD, SEM‐EDS, and XPS, and the electrochemical performance and lifetime of the RuO2/Ti and RuO2‐IrO2/Ti was verified via an electrochemical workstation. Uniform and stable RuO2/TiO2 and RuO2‐IrO2/TiO2 were synthesized successfully for the electrolysis of the NaCl solution.

“…The corresponding mechanisms have been elucidated and show the possibility of oxidizing many forms of phosphorus. [32][33][34] Consequently, to improve the digestion procedure to determine TP, we establish herein a rapid and energy-saving method using an advanced oxidation process to generate hydroxyl radicals (cOH) with a b-PbO 2 electrode, which shows a high hydroxyl radical utilization. 35 cOH is one of the most powerful oxidizing agents, and the standard electrode potential is about 2.73 vs. SHE/V.…”
