Figures-of-merit for the technical development and application of advanced oxidation technologies for both electric- and solar-driven systems (IUPAC Technical Report)

Abstract: Advanced oxidation technologies (AOTs), which involve the in situ generation of highly potent chemical oxidants, such as the hydroxyl radical (áOH), have emerged as an important class of technologies for accelerating the oxidation (and hence removal) of a wide range of organic contaminants in polluted water and air. In this report, standard figures-of-merit are proposed for the comparison and evaluation of these waste treatment technologies. These figures-of-merit are based on electric-energy consumption (for … Show more

“…Since photocatalysis of aqueous organic pollutant is an electric-energy-intensive process, and electric energy can represent a major fraction of the operating costs, simple figuresof-merit based on electric energy consumption can be very useful and informative. The photochemistry commission of the International Union of Pure and Applied Chemistry (IUPAC) proposed a figure-of-merit (or more appropriately, an Efficiency Index, as it compares electrical efficiency of different AOPs) for UV-based AOPs [57]. Electrical energy per order (E EO ) compares electrical efficiency of different UV-based AOPs and is a measure of the electrical efficiency of an AOP system.…”

“…Na cinética de primeira ordem, o logaritmo natural da concentração dos reagentes deve diminuir linearmente com o tempo (Atkins, 1988). Usualmente o limiar de concentração (Bolton et al, 2001) alta ou baixa é 100mg.L -1 , sendo esta a concentração estudada neste trabalho. A Figura 5 indica um comportamento exponencial da concentração em função do tempo, dada a linha de tendência exponencial de primeira ordem com R 2 = 0,99401, onde R indica o coeficiente de correlação.…”

“…Na Figura 6 tem-se o comportamento obtido experimentalmente, na qual se pode verificar que há um comportamento de primeira ordem. O resultado obtido com a degradação do corante vermelho bordeaux é concordante com dados obtidos pela literatura (Araújo, Yokoyama & Teixeira, 2006;Bolton et al, 2001;Catanho, Malpass & Motheo, 2006). A equação da reta (linha de tendência linear) é y(t) = 0,23827 -0,2251 *t, , com coeficiente de correlação R = 0,99033.…”
