“…In electrochemical treatment processes, organic pollutants could be removed from wastewater by indirect and direct mechanisms (Brillas and Martínez-Huitle, 2015;Comninellis and Chen, 2010;Körbahti and Artut K, 2010;Körbahti and Taşyürek, 2015;Panizza and Cerisola, 2009). Indirect oxidation occurs in the liquid bulk phase by the mediated oxidants, and direct oxidation at the anode surface (Brillas and Martínez-Huitle, 2015;Comninellis and Chen, 2010;Körbahti and Artut K, 2010;Körbahti and Taşyürek, 2015;Panizza and Cerisola, 2009). Most electrochemical processes are based on indirect oxidation because direct oxidation of organic pollutants are very slow on inert anodes due to the limiting reactions and reaction kinetics (Tarr, 2003;Rajeshwar and Ibanez, 1997).…”

In this study, pH and pH change in the electrochemical oxidation of imidacloprid (IMD) pesticide using boron-doped diamond (BDD) electrodes was investigated in the presence of Na2SO4 electrolyte. The process parameters were operated as imidacloprid concentration (40-200 mg/L), electrolyte concentration (2-10 g/L), current density (4-20 mA/cm 2) and reaction temperature (20-60C). pH and pH values increased with increasing Na2SO4 concentration, current density, and reaction temperature, and decreasing the imidacloprid concentration at 120 min reaction time. The results of this study showed that the pH of the wastewater solution maintained the local pH discharge limits between 6 and 9 after the electrochemical oxidation.

BACKGROUND: Nowadays, due to the inappropriate use of antibiotics, significant quantities have been detected in environmental samples. Therefore there is a need for a technology to eliminate the accumulation of pharmaceuticals in receiving water bodies. In recent years electrochemical oxidation showed superior efficiency for the purification of water from pharmaceuticals. RESULTS: boron doped diamond (BDD) showed better efficiency than platinum electrode and stainless steel for the degradation of 500 g L−1 tetracycline (TC) with 0.1 mol L −1 ·Na 2 SO 4 . The presence of 200 mg L −1 bicarbonates decreased the apparent kinetic constant from 0.328 to 0212 min −1 . Instead, the addition of 200 mg L −1 NaCl increased the kinetic constant by almost four times, while the presence of 10 mg L −1 of humic acid decreased the kinetic constant by 18%. The process was favored in real environmental matrices like bottled water and wastewater in comparison with ultrapure water. The use of BDD as both anode and cathode enhanced the efficiency by almost 20%. The presence of UVA or solar radiation increased the decomposition of tetracycline by 14%. Changes in toxicity to Vibrio fisheri bacteria during treatment of TC in the secondary effluent are mainly attributed to the formation of intermediates of the water matrix itself and does not follow the TC removal. CONCLUSIONS: Electrochemical oxidation was favored for removal of TC in real water matrices due to the presence of chlorides. The use of BDD as both anode and cathode with simultaneous solar irradiation is a promising technology for water remediation from TC.

Catechol is a substance that is commonly found in wastewaters from a variety of sectors including paper, paint, petroleum, dyes, antioxidants, pesticides, iron and steel, solvents, nylon, detergent, textile, plastic, rubber, cosmetics, and medicine. In this study, sequential electrochemical and chemical multi-polymerization of catechol was investigated for environmental pollution abatement. The effect of operating parameters like catechol concentration (2–10 g/L), ammonium persulphate (APS) concentration (2–10 g/L) and reaction temperature (20–60 °C) were evaluated using response surface methodology. Catechol concentration was determined using HPLC in a gradient mobile phase. The electrochemical behavior of the polymer was investigated by cyclic voltammetry (CV). The structural and morphological properties of polycatechol were characterized by Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy with energy dispersive X-ray (SEM–EDX) analysis. It was observed from the SEM images a polymeric structure developed from a crystalline and heterogeneous structure when the APS concentration increased. Similarly, it was seen in SEM images that the polymers transitioned from a bulk and heterogeneous structure to a homogeneous structure as the temperature increased, and back to a heterogeneous structure as the catechol concentration increased. It was also found that catechol removal increased and reaction selectivity decreased by increasing the reaction temperature. The optimum operating conditions were found as 4 g/L catechol concentration, 9.5 g/L APS concentration, 30 °C reaction temperature with 100 cycles at 50 mV/s of electrochemical polymerization and 72 h of chemical polymerization. The results of this study show the potential of challenging new routes not only facile polymerization of organic monomers but also to decrease the undesirable pollutant concentration in the wastewater.
