Abstract

Advanced oxidation processes have a significant impact, particularly on degradation-resistant pollutants. Furthermore, the efficiencies achieved through advanced oxidation processes encourage new studies The study utilized paracetamol, a form of micropollutant, as a pollutant. The optimization study was conducted on a bismuth (Bi)-doped Ti/IrO2-RuO2 electrode and its combination with various oxidation processes. In this study, the total organic carbon (TOC) removal efficiency was found to be 42% with bismuth-doped electrodes, while this value was 28% for undoped electrodes. Furthermore, it was observed that the oxygen overpotential of the electrodes increased, resulting in a more than eight-times increase in service life. Photocatalytic-assisted (UV-A) electrooxidation studies showed that the TOC removal efficiency with the addition of ZnO was approximately 55%. However, the expected improvement was not observed in the ultrasound (US)-assisted process; on the contrary, the removal efficiency decreased as the applied power to the system increased. In this study, it was seen that Bi-doped Ti/IrO2-RuO2 electrodes gave promising results.

Özet

İleri oksidasyon prosesleri özellikle degredasyona dirençli kirleticiler üzerinde önemli bir etkiye sahiptir. Ayrıca, ileri oksidasyon prosesleri sayesinde elde edilen verimler de yeni çalışmalara cesaret vermektedir. Bu çalışmada model kirletici olarak, bir mikrokirletici olan parasetamol kullanılmıştır. Optimizasyon çalışması bizmut (Bi) katkılandırılmış Ti/IrO2-RuO2 elektrot ve bu electrodun çeşitli oksidasyon prosesleriyle ortak çalışmaları üzerine yapılmıştır. Bu çalışmada, bizmut katkılandırılmış elektrotlar ile toplam organic karbon (TOK) giderim veriminin %42 bulunurken, katkılandırılmamış elektrotlarda ise bu değerin %28 olduğu görülmüştür. Ayrıca elektrotlarda oksijen aşırı gerilimi artarken servis ömrünün de 8 katından fazla arttığı görülmüştür. Fotokatalitik destekli (UV-A) elektooksidasyon çalışmalarında ise, ZnO ilavesiyle TOK giderim veriminin yaklaşık %55 olduğu görülmüştür. Ancak, ultrases (US) destekli proseste beklenen iyileşme gözlemlenmemiş; aksine, sisteme uygulanan güç arttıkça giderim verimi azalmıştır. Bu çalışmada Bi-katkılı Ti/IrO2-RuO2 elektrotların umut verici sonuçlar verdiği görülmüştür.
