Optimization of the combined adsorption/photo-Fenton method for the simultaneous removal of phenol and paracetamol in a binary system

Fabrication of cotton textile waste-based magnetic activated carbon using FeCl3 activation by the Box–Behnken design: optimization and characteristics

“…27 Recently, the response surface methodology, such as the Box-Behnken Design (BBD), has been commonly selected to assist experimental design. 28 Compared to other methods, the minimal amount of experimental data is demanded in the BBD, which exhibits excellent predictability within the design space and can analyze the interactions between different variables. 29,30 Besides, the BBD is a rotatable or nearly rotatable design.…”

Correlation between degradation pathway and toxicity of acetaminophen and its by-products by using the electro-Fenton process in aqueous media

“…Recently, textural modification of carbon felt (Le et al, 2016) and graphene deposition on graphite substrates (Le et al, 2015a&b) have shown a great potential to enhance mineralization of the azo dye acid Orange 7 and ACE by the electro-Fenton (EF) process. Derived Fenton processes have also already proved to be efficient methods to degrade ACE from water: combined EF and photo-Fenton using a double cathode electrochemical cell (de Luna et al, 2012), coupling adsorption and photo-Fenton using nano-zeolites and cobalt ferrite nanoparticles (Irani et al, 2015), bio-electrochemical degradation in a microbial fuel cell-Fenton system (Zhang et al, 2015), or other methods relevant to the photo-Fenton process (Trovó et al, 2008;Trovo et al, 2012;Cabrera Reina et al, 2015;Rad et al, 2015). As a more detailed example, Sirés et al could totally mineralize ACE in CO2 after 6 h of treatment by using the catalytic action of Fe 2+ , Cu 2+ and UVA light to generate hydroxyl radicals.…”

“…In addition, many by-products including aromatic compounds as well as carboxylic acids were adequately detected, such as hydroquinone, pbenzoquinone, 1,2,4-trihydroxybenzene, 2,5-dihydroxy-p-benzoquinone and tetrahydroxy-pbenzoquinone, maleic, fumaric, succinic, lactic, oxalic, formic and oxamic acids. In addition, the combination of adsorption and photo-Fenton method by Irani et al could lead to 99.80% of paracetamol removal in 30 min (Irani et al, 2015).…”

Activated carbon obtained from sapelli wood sawdust by microwave heating for o-cresol adsorption

“…There are many techniques for treatment of wastewater contaminated with phenolic compounds, including biological processes [5,6], coagulation [7], membranes [8], electro-Fenton and photoelectro-Fenton treatments [9], ozonation [10], oxidation [11,12], and adsorption [13][14][15][16]. However, application of these methods is restricted since they are very expensive and involve high initial capital and operational costs.…”
