“…The use of microorganisms to be injected in the cable and capable of digesting the oil (bioremediation) has been intensively studied, but open issues such as the choice of effective microorganisms, the need for nutrient supply, and the lack of oxygen still remain to be solved [3,4,5]. Another possible in situ approach is the chemical oxidation of the oil using different reagents [6,7,8,9,10]. However, this method is far from being applicable as it entails the use of chemicals and it involves a safety risk associated with the production of gases in a closed environment along with the possible occurrence of nonspecific reactions.…”

“…A maior parte das pesquisas realizadas com o biodiesel está relacionada com o seu potencial energético, estabilidade térmica, de pré-tratamentos, tornar esta matéria biodegradável (ALOUI; KCHAOU;SAYADI, 2009;MORAIS;ZAMARA, 2005). Um dos POA mais promissores consiste na reação entre íon ferroso (Fe 2+ ) e peróxido de hidrogênio (H 2 O 2 ) em meio ácido, conhecida como a "reação de Fenton", que gera os radicais hidroxila (•OH), de elevado potencial padrão de redução, com ataque pouco ou não seletivo às espécies presentes no meio reacional, em uma reação espontânea e que ocorre na ausência de luz (SILVA et al, 2005;DENG;ENGLEHARDT, 2006). Conforme Deng e Englehardt (2006), a dosagem do H 2 O 2 depende da carga orgânica inicial do composto orgânico a ser tratado, expressa em termos da demanda química de oxigênio (DQO), estabelecendo uma dosagem ótima DQO 0 :H 2 O 2 de 1:2.…”
