Over the past decades, the treatment of textile and dyeing
wastewater with severe color, low biodegradability and high toxicity
has been one of the major concerns in environmental protection
[1–3]. Rhodamine B (RhB) is a nitrogen-containing dye which
appears to undergo natural reductive anaerobic degradation to
yield potentially carcinogenic aromatic amines [4]. In order to
eliminate the negative environmental impact of RhB, advanced oxidation
processes (AOPs) was proposed as an alternative approach
since conventional biological wastewater treatment processes are
not efficient to remove RhB [5,6].
