“…To eliminate the drawbacks, Advanced Oxidation Processes (AOPs) have been put into practice as potential remediation to address organic pollution in soil and water. This method is based on radical mechanism; hydroxyl radical(·OH) and sulfate radical(SO 4 • − ), are two typical radical oxidants, which are kinetically slow in ordinary conditions and often induced by photolysis [3] , microwaves [4] , heat [5,6] , electron beam [7,8] , ultrasonication [9] , alkaline [10,11] etc. Via chemical reaction with those emerging oxidant, organic pollutants in wastewater difficult to keep away are converted to non-toxic and small molecules, or directly mineralized into harmless inorganic molecules such as CO 2 , H 2 O.…”

“…24,42 Assim, o percentual de remoção da coloração da solução do PON 2R em função da densidade de corrente aplicada foi calculado a partir da Equação 1. 43 (1) em que Abs t é a absorbância em um determinado tempo de eletrólise e Abs 0 é a absorbância da solução antes da eletrólise, com os valores de absorbância sendo acompanhados pela banda com λ máx = 505 nm, responsável pela coloração do PON 2R. A Figura 4 apresenta os percentuais de descoloração em função da densidade de corrente aplicada para os diferentes eletrodos.…”
