| This study investigated the effects of the electrolytic treatment in the simulated wastewater with aromatic amine n-phenyl-n-isopropyl-p-phenylenediamine (Flexzone 3P®) using Ti/TiRuO2 electrodes under 0.025 A/cm² (DC) for different electrolysis durations (5; 15; 30; 45 and 60 min). Conductivity, pH, UV-visible spectra, gas chromatograms, toxicity and biodegradation tests were carried out. During the electrolytic treatment the pH decreased and conductivity increased slightly. After 60 min of electrolysis, the concentration of Flexzone 3P decreased by 65.1%. UV-vis spectra and chromatograms of simulated wastewater showed changes in the molecular structure of the aromatic amine. After 5 and 15 min of electrolysis, the simulated wastewater containing the... |
