Photodegradation of malachite green and malachite green carbinol under irradiation with different wavelength ranges

Laccase-Catalyzed Decolorization of Malachite Green: Performance Optimization and Degradation Mechanism

“…Besides pathway I, LacA also mediated MG degradation via a second pathway (pathway II). In this pathway, MG was first hydroxylated to its carbinol form [ 34 ], which was quickly broken down at the bond between the central carbon atom and the N , N -dimethylamino phenyl ring into (dimethyl amino-phenyl)-phenyl-methanone and N , N -dimethylaniline. (dimethyl amino-phenyl)-phenyl-methanone was then sequentially N -demethylated to (amino phenyl)-phenyl methanone.…”

Investigation of novel material for effective photodegradation of bezafibrate in aqueous samples

“…This role is mostly fulfilled by transition metal oxide semiconductors, among which titanium dioxide (TiO 2 ) is one of the most widely used. Apart from the removal of pharmaceuticals (Deegan et al 2011), dyes (Regulska and Karpińska 2012; Regulska et al 2013; Shang et al 2011; Fan et al 2011; Fischer et al 2011), cyanides (Kabra et al 2004), malodorous compounds (Kabra et al 2004), fungicides (Topalov et al 1999), herbicides (Topalov et al 2000) and pesticides (Assalin et al 2010), TiO 2 was also satisfactorily applied in a destruction of bacteria, viruses (Henderson 2011) and cancer cells (Rozhkova et al 2009). What is more, due to its photocatalytic activity, TiO 2 was deeply researched in the field of self-cleaning (Sökmen et al 2011), self-sterilizing (Hashimoto et al 2005), highly hydrophilic and anti-fogging surfaces (Hashimoto et al 2005).…”

Ag3PO4/TiO2‐assisted degradation of malachite green in aqueous solution treated by dielectric barrier discharge plasma

“…However, MG is a hazardous agent which can cause toxic effects, for instance, marked cytotoxicity, cell transformation, lipid peroxidation and potential carcinogenesis . Although MG has been banned in aquaculture in the USA and Europe, its low cost and high efficiency make its illegal and heavy use likely . Because the 5‐day biochemical oxygen demand (BOD 5 ) of MG is almost equal to zero, MG is not efficiently biodegradable and is ineffectively degraded by conventional biological treatment technologies .…”

“…3,4 Although MG has been banned in aquaculture in the USA and Europe, its low cost and high efficiency make its illegal and heavy use likely. 5 Because the 5-day biochemical oxygen demand (BOD 5 ) of MG is almost equal to zero, MG is not efficiently biodegradable and is ineffectively degraded by conventional biological treatment technologies. 6,7 A number of studies focusing on the photocatalytic degradation of MG with TiO 2 , 8,9 anaerobic degradation with Shewanella decolorationis NTOU1 10 and the electro-Fenton reaction with Fe 3+ , 11 indicate that separate advanced oxidation processes (AOP) have weaknesses, such as low degradation efficiency, high investment, formation of undesirable by-products, etc.…”
