20.500.12556/RUL-171108 Electrodegradation of selected water contaminants efficacy and transformation products The electrooxidation (EO) of three important environmental contaminants, anticorrosive 1H-benzotriazole (BTA), plasticizer dibutyl phthalate (DBP), and non-ionic surfactant Triton X-100 (tert-octylphenoxy[poly(ethoxy)] ethanol, t-OPPE), was studied as a possible means to improve their elimination from wastewaters, which are an important emission source. EO was performed in a batch reactor with a boron-doped diamond (BDD) anode and a stainless steel cathode. Different supporting electrolytes were tested: NaCl, H2SO4, and Na2SO4. Results were analysed from the point of their efficacy in terms of degradation rate, kinetics, energy consumption, and transformation products. The highest degradation rate, shortest half-life, and lowest energy consumption was observed in the electrolyte H2SO4, followed by Na2SO4 with only slightly less favourable characteristics. In both cases, degradation was probably due to the formation of persulphate or sulphate radicals. Transformation products (TPs) were studied mainly in the sulphate media and several oxidation products were identified with all three contaminants, while some evidence of progressive degradation, e.g., ring-opening products, was observed only with t-OPPE. The possible reasons for the lack of further degradation in BTA and DBP are too short of an EO treatment time and perhaps a lack of detection due to unsuitable analytical methods for more polar TPs. Results demonstrate that BDD-based EO is a robust method for the efficient removal of structurally diverse organic contaminants, making it a promising candidate for advanced water treatment technologies. 1H-benzotriazole dibutyl phthalate Triton X-100 electrooxidation boron-doped diamond electrode degradation rate kinetics energy consumption transformation products LC-MS/MS 1H-benzotriazol dibutil ftalat Triton X-100 elektrooksidacija z borom dopirana diamantna elektroda hitrost razgradnje kinetika poraba energije transformacijski produkti LC-MS/MS true false true Angleški jezik Slovenski jezik Članek v reviji 2025-08-05 13:33:09 2025-08-05 13:33:11 2025-08-06 04:01:38 0000-00-00 00:00:00 2025 0 0 23 str. iss. 15, art. 8434 Vol. 15 Aug. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-08-01 628.349:66.087.3:543.544.5 2076-3417 10.3390/app15158434 244417795 RAZ_Malinovic_Borislav_N._2025.pdf RAZ_Malinovic_Borislav_N._2025.pdf 1 98FDAF96B14B79D6B29EEACE62088CFD 06c7770f11ea52cf478847ddcf15c7d97000235a5a98fff92628e49ef0b097d2 00b74ccb-71f3-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=213923 https://www.mdpi.com/2076-3417/15/15/8434 1 e873ecf6-71ef-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=213911 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
