“…The TiO 2 -mediated photocatalysis process has been successfully used to degrade pollutants during the past few years [4][5][6][7][8][9][10][11][12][13][14][15][16]. TiO 2 is broadly used as a photocatalyst because of its nontoxicity, photochemical stability, and low cost [17][18][19][20].…”

“…In the past decade, different approaches have been utilized to remove or degrade the wastewater containing CV including biological decolouration [3][4][5], adsorption [6][7][8][9], and some advanced oxidation processes (AOPs) such as photo-Fenton reaction [10][11][12], TiO 2 -mediated photocatalytic degradation using visible light irradiation [13] and UV irradiation [14,15], and TiO 2 photocatalytic degradation using microwave powered electrodeless discharge lamps [16][17][18][19]. However, each technology has its own limitations.…”

“…A toxicidade destes, baseia-se em sua reatividade com espécies oxigenadas ou excitação durante terapias fotodinâmicas. Assim, seu potencial carcinogênico encontra-se correlacionado a sua oxidação através de sistemas específi cos, ou pela ação da enzima peroxidase, produzida pela tireóide, gerando aminas primárias e aromáticas [3].…”

“…Assim, e considerando o alto risco de descarte deliberado deste tipo de corante em corpos d'água, sistemas aqüíferos e mananciais de abastecimentos, várias iniciativas têm sido desenvolvidas a fi m de degradar este tipo de poluente [1][2][3][7][8][9][10][11][12][13][14].…”
