“…The objective of this work is to study the adsorption of H‐ and γ‐acid onto highly porous AC derived from wild almond shells. Treatment of H‐acid wastewater has been carried out by various researchers using degradation by Alcaligenes latus cells , wet air oxidation , photocatalysis , photo‐Fenton reagent , ozonation , extraction and stripping , etc. However, there are no reports on the adsorptive removal of these important naphthalenesulfonic acids (NSAs) from wastewater.…”

Activated carbon was prepared from wild almond shells using phosphoric acid as an activating agent. The BET surface area and the pore volume were found to be 1133.25 m2/g and 1.41 cm3/g, respectively. Batch adsorption of two naphthalene dye intermediates, H‐ and γ‐acid was carried out using prepared activated carbon. The maximum adsorption capacities were found to be 911 and 809.4 mg/g, respectively, at 65°C. Freundlich isotherm fitted well the equilibrium data, indicating favorable adsorption of both the acids. Adsorption was controlled by the external mass transfer and intraparticle diffusion. Thermodynamic analysis showed that the adsorption was physical, spontaneous, and endothermic in nature. © 2016 American Institute of Chemical Engineers Environ Prog, 36: 38–44, 2017

“…Examples of 2 Advances in Environmental Chemistry AOPs include the use of hydrogen peroxide with ultraviolet light (H 2 O 2 /UV) to treat hazardous compounds [7], Fenton and photo-Fenton reagent (H 2 O 2 /Fe 2+ ) [8][9][10], semiconductor photocatalysis [11], and the sonolysis process using ultrasonic irradiation [12]. Among various AOPs, the Fenton reagent is one of the most effective methods for treating various industrial effluents including wastewater [13,14] and oily wastewater [15]. Previous work by the authors has involved the application of Fenton and the photo-Fenton reagents for the treatment of water polluted with diesel oil emulsion [10,16].…”

Establishing a treatment process for practical and economic disposal of car wash wastewater has become an urgent environmental concern. Photo-Fenton's process as one of the advanced oxidation processes is a potentially useful oxidation process in treating such wastewater. Lab-scale experiments with UV source, coupled with Fenton's reagent, showed that hydrocarbon oil is degradable through such a process. The feasibility of photo-Fenton's process to treat wastewater from a car wash is investigated in the present study. A factorial design based on the response surface methodology was applied to optimize the photo-Fenton oxidation process conditions using chemical oxygen demand (COD) reduction as the target parameter to optimize. The reagent (Fe 2+ and H 2 O 2 concentration) and pH are used as the controlling factors to be optimized. Maximal COD reduction (91.7%) was achieved when wastewater samples were treated at pH 3.5 in the presence of hydrogen peroxide and iron in amounts of 403.9 and 48.4 mg/L, respectively.

“…Oxidation with Fenton's reagent (Fe 2C , H 2 O 2 ) combined with coagulation results in 90% decrease in COD (initial value e 60 000 mg O 2 /l) [4,5]. Oxidation with Fenton's reagent combined with UV radiation in the presence of TiO 2 yields a 60% decrease in COD from 300 mg O 2 /l [6]. In the case of treatment of 2-naphthalenesulphonate sodium at the concentration of 26 mg/l, application of ozonation results in 15% decrease in TOC.…”
