“…Potassium permanganate (Mn(VII)) is a strong and active oxidant and has been extensively used in drinking water and wastewater treatment practices for decades (He et al, 2010;Aleboyeh et al, 2009). There have been reports that Mn(VII) could oxidize a wide range of emerging environmental micropollutants, such as chlorophenol, ciprofloxacin, lincomycin, triclosan, estradiol, bisphenol A and sulfamethoxazole (Gao et al, 2014;Liu et al, 2009;Hossain and McLaughlan, 2012;Hu et al, 2011;Zhang et al, 2013;Jiang et al, 2012).…”

“…9,14 Os corantes azoicos fazem parte de uma das classes mais importantes de corantes sintéticos comerciais, devido a sua solubilidade, baixo custo, estabilidade e variedade de cores. Devido a esses fatores, são amplamente utilizados em diversos tipos de indústrias, tais como têxteis, 15 cosméticos, couro, papel e alimentos. Os compostos azo são resistentes à degradação aeróbia e em condições anaeróbias, a ligação azo é reduzida gerando aminas aromáticas, que são incolores, mas também podem ser tóxicas e potencialmente cancerígenas.…”

“…The development of effective, cheap, and easy-to-handle process is of crucial importance for the treatment of dye wastewater. KMnO 4 has been proposed for the treatment of dye wastewater [17,18]. Xu et al reported that KMnO 4 at pH 0.5 contributed to satisfactory decolorization of different dyes and the increase of BOD 5 /COD [17].…”
