The UV/H2O2 advanced oxidation process in UV disinfection units : removal of selected phosphate esters by hydroxyl radical
… esters through hydroxyl radical generated by the UV/H202 process applied at a UV disinfection unit was selected for evaluation. The second-order rate constants of the reactions of two phosphate esters, Tri(2-butoxyethyl) phosphate (TBEP) and Tri-2-chloroethyl phosphate (TCEP) , with hydroxyl …

Understanding the impact of the scavenging capacity on costs of the UV chlorine advanced oxidation process for drinking water treatment using the external calibration method and the development of cost curves.
UV-driven advanced oxidation processes (e.g. UV/H2O2, UV/Cl) that couple UV irradiation with oxidizing chemicals to generate highly reactive species such as ·OH radicals and reactive chlorine species are increasingly being recommended for the removal of recalcitrant organic contaminants in drinking …

Remoção de desreguladores endócrinos em água de abastecimento
… a sua identificação. Os processos foto- Fenton, UV/H2O2, UV/TiO2 e ozonização foram eficientes na remoção dos hormônios, mas devido ao elevado tempo de contato e a possibilidade de toxicidade do TiO2, destaca-se a ozonização. Ademais, mais estudos devem ser realizados, principalmente para o …

The Effect of Natural Organic Matter on UV/H<sub>2</sub>O<sub>2</sub> Treatment and the Effect of UV/H<sub>2</sub>O<sub>2</sub> Treatment on Natural Organic Matter
<p>Ultraviolet light with hydrogen peroxide (UV/H<sub>2</sub>O<sub>2</sub>) produces hydroxyl radicals that degrade organic micro-pollutants. However, radicals react non-selectively with natural organic matter (NOM). This research effort quantified the effect of NOM variation on the efficiency of …
