Electrochemical Incineration of Organic Pollutants for Wastewater Treatment: Past, Present and Prospect

Electrochemical Oxidation of Methylene Blue in Aqueous Solution

“…It is also being used for Food industry as well like olive oil and dairy manure. [4]. Because of presence of sodium chloride in textile dyes the process of electrochemical oxidation is very easy to use without any addition of chemicals.…”

Electrochemical oxidation of fipronil contaminated wastewater by RuO2/IrO2/TaO2 coated titanium anodes and sorbent nano hydroxyapatite

“…The increase in hypochlorite ion also approaches equilibrium with degradation of organics present in the effluent has reported that an increased current density during electro oxidation enhanced chlorine generation, which could probably be responsible for subsequent removal of pollutants [47]. The organics are selectively oxidized in the presence of chemisorbed active oxygen, whereas it will be completely mineralized to CO 2 and H 2 O in the presence of physicsorbed active oxygen [48]. The efficient removal of organics in the presence of a triple oxide coated electrode may be attributed to its effective generation of HOCl, which is a stronger oxidant compared to oxygen and have observed a strong catalytic effect of chloride ion in the conversion of organic pollutants to innocuous CO 2 and H 2 O [49].…”

Estudo da degradação do dietil ftalato por processo eletroquímico com ânodo dimensionalmente estável em sistemas aquosos

“…É importante saber que durante o tratamento eletroquímico de efluentes aquosos, ambos mecanismos de oxidação podem coexistir(CHIANG;CHANG;WEN, 1995).Figura 4 -Processo de oxidação direta e indireta no tratamento eletroquímico. Fonte: Adaptação de CHIANG; CHANG; WEN, 1995, p. 673.Nos processos de oxidação eletroquímica, o material do eletrodo é muito importante, pois disto depende a eficiência e seletividade do processo, mas este parâmetro afeta muito mais as reações anódicas(KLAMKLANG et al, 2012) Comninellis (1994). apresentou o mecanismo da oxidação anódica, processo fundamental no tratamento eletroquímico.…”
