Modeling azo dye removal by sono-fenton processes using response surface methodology and artificial neural network approaches

Backpropagation neural networks modelling of photocatalytic degradation of organic pollutants using TiO2‐based photocatalysts

“…The excellent predictability of the ANN model used for prediction of dye degradation has been reported by Baştürk and Alver. 43 The authors employed RSM and ANN for modelling the removal of azo dye by the sono-Fenton process. The study revealed that ANN, with a smaller predictive error, displayed a more accurate prediction compared to RSM.…”

Hazardous wastes treatment technologies

“…The results indicated ultrasound field enhanced photoactivity due to improved mass transfer and increased charged electron-hole separation. Basturk and Alver (2019) studied the decolorization efficiency by sono-Fenton method using H 2 O 2 and Fe 2+ reagents, under specific initial pH, ultrasound power, and ultrasound frequency.…”

Fenton Reagent for Organic Compound Removal in Wastewater

“…There is room for modification in the Fenton process, which includes, but is not limited to the utilization of ultrasound (Sono-Fenton process -SF) [8,[11][12][13][14], anodic oxidation (Electro-Fenton Process -EF) [15][16][17][18], using UV light and adding ferric or ferrous oxalate ions (Photo-Fenton process -PF) [19][20][21][22][23], utilizing both ultrasound and ultraviolet light (Sono-Photo-Fenton process -SPF) [24][25][26], utilizing both ultrasound and anodic oxidation (Sono-Electro-Fenton process -SEF) [27], and utilizing a combination of electrochemical and photochemical properties of UV radiation (Photo-Electro-Fenton process -PEF) [2]. Other notable modifications have been developed, such as Solar-Photo-Electro-Fenton process (SPEF) [28], Peroxi Coagulation (PC), Photo-Peroxi Coagulation (PPC), Photo-Electro Catalysis (PEC), Ferred Fenton process, and Electrochemical Peroxidation (ECP) [29].…”

“…While the Fenton reaction uses Fe 2+ ions reacting with H2O2 to form oxidizing agent hydroxyl radicals, the ferric ions produced can also react with hydrogen peroxides to reform ferrous ions (equations [11][12][13][14]: Other researchers, such as Rodríguez-Narváez et al [67] studied conventional Fenton reactions as well as Fenton-like reactions for use in L-proline degradation, and found that the Fenton-like systems produced better results. Both Fenton-like reactions, homogenous and heterogenous, gave a higher Lproline removal rate compared to conventional Fenton reaction with the same operating conditions.…”
