Electrochemical degradation of the antihypertensive losartan in aqueous medium by electro-oxidation with boron-doped diamond electrode

Recent advances in electrocatalysts for halogenated organic pollutant degradation

“…Nevertheless, Na 2 SO 4 manifested a better performance than NaCl in the electrooxidation of losartan with a BDD electrode. 126 Using Na 2 SO 4 as supporting electrolyte, the mineralization ratio (67%) was higher than that of the NaCl system (56%). Interestingly, Mena et al 127 designed an experiment to clarify the contribution of hydroxyl radicals and electrogenerated sulfur-based radicals (e.g., peroxodisulfate) in the degradation of three different ionic liquids (ILs) using a BDD anode.…”

“…Specifically, the degradation kinetics and efficiency, as well as the degradation pathways are sensitive to electrolytes. [124][125][126] The Compared to other electrolytes, NaCl led to an appreciably faster degradation of enrofloxacin, and the most initial intermediates were chlorinated. Nevertheless, Na 2 SO 4 manifested a better performance than NaCl in the electrooxidation of losartan with a BDD electrode.…”

Effect of the sp3/sp2 Ratio in Boron‐Doped Diamond Electrodes on the Degradation Pathway of Aniline by Anodic Oxidation

“…Anodic oxidation (AO) is one of the most popular processes among EAOPs. It consists of applying a potential/current between two electrodes immersed in a solution to generate various strong oxidant species such as .…”

“…Electrochemical advanced oxidation processes (EAOPs) are wellknown green technologies that have been widely used in the last few years, [1][2][3][4] as they are able to eliminate pollutants of emerging concern and persistent pollutants, such as drugs, [5][6] pesticides or fungicides, [7][8] dyes, [9][10] as well as other organic compounds resistant to photo and biodegradation from aqueous matrices. [11][12] Anodic oxidation (AO) [13][14][15] is one of the most popular processes among EAOPs. It consists of applying a potential/ current between two electrodes immersed in a solution to generate various strong oxidant species such as * OH, [16] persulfate anion, [17] hydrogen peroxide [18] and ozone, [19] as well as active chlorine species such as molecular chlorine, hypochlorous acid and hypochlorite ion.…”

Emerging Pollutants – Part II: Treatment

“…For DEP degradation and TOC removal, the boron-doped diamond anode had a better effect than PbO2 anode or Pt anode. After 210 min treatment, total mineralization of 50 mg/L DEP could be obtained in both 0.1 M Na2SO4 solution and municipal wastewater treatment plant secondary effluent, by electrolysis with boron-doped diamond as anode Salazar et al (2016). studied the degradation of the antihypertensive losartan in aqueous solution by electro-oxidation with boron-doped diamond electrode.Process parameters, including supporting electrolyte, pH, current density and initial drug concentration were investigated and optimized.…”
