Combined heterogeneous and homogeneous photodegradation of a dye using immobilized TiO2 nanophotocatalyst and modified graphite electrode with carbon nanotubes

Preparation and characterization of graphene oxide/TiO2 blended PES nanofiltration membrane with improved antifouling and separation performance

“…The presence of synthetic dyes in the wastewater of these industries causes many environmental problems [35]. Considering environmental and economic issues, it is unacceptable to discharge these effluents to recipient streams without proper treatment because of both volume and composition of the colored wastewater.…”

Electrochemical reactivity of Ponceau 4R (food additive E124) in different electrolytes and batch cells

“…The large ability of both kinds of EAOPs to quickly decolorize and even completely mineralize azo dye solutions has been confirmed [9,[23][24][25][26][27][28][29][30][31][32][33][34]. Among the operating parameters that determine their performance, the supporting electrolyte is critical because different inorganic salts are present in real wastewater.…”

Heterogeneous Fenton process by natural pyrite for removal of a textile dye from water: Effect of parameters and intermediate identification

“…GC-MS analysis was performed to determine the intermediate products formed during the RO29 degradation process. Preparation of sample for GC-MS analysis has been discussed in our previous work [12] and it should be mentioned that silylated products, which could be detected more conveniently, were prepared by adding N,O-bis-(trimethylsilyl)acetamide after extraction. The solutions were analyzed by GC-MS apparatus (Agilent 6890 gas chromatography and 5973 mass spectrometer, Palo Alto, Canada) with the following instrumental conditions: inlet temperature: 250°C; transfer line temperature: 250°C, detector temperature: 300°C and energy of electron: 70 eV.…”
