“…Most AOPs are based on the generation of HO Å radicals in the medium, which follow from traditional methods to newly scrutinized biological modus operandi HO Å (E 0 = 2.720 V vs. NHE) [6][7][8][9][10]. Key AOPs include heterogeneous and homogeneous photocatalysis based on near ultraviolet (UV) or solar visible irradiation, electrolysis, ozonation, the Fenton's reagent, ultrasound, and wet air oxidation, while less conventional but evolving processes include ionizing radiation, microwaves, pulsed plasma, and the ferrate reagent [11][12][13][14][15]. AOPs although making use of different reacting systems, are all characterized by the same chemical feature: production of OH radicals.…”

In the present research, the degradation of tylosin (TYL) by nano Ag/S 2 O 2À 8 process under various reaction conditions was investigated. The experiments were performed in a batch reactor, using nanosilver as a catalyst. Effects of pH, persulfate concentration, temperature, and catalytic nano Ag on the degradation efficiency of TYL by persulfate are examined. For treatment of solutions containing 50 mg/L of TYL, the optimum obtained conditions were: 0.4 g/L of nano Ag, 100 mM of the KPS, initial pH of 6.0, and temperature of 40˚C. The degradation of TYL by nano Ag/S 2 O 2À 8 oxidation process has been found to follow the pseudo-first-order kinetic model. Finally rate equation for TYL degradation using Langmuir-Hinshelwood kinetic model is: r ¼ 9630:5 exp À 32:552 RT C 0:9925

“…The most techniques used in the AOP's are Fenton's reagent, UV/Ozone and UV/H 2 O 2 . As reported by Harimurti et al, Dutta et al, and Omar et al, Fenton's reagent has been used for treatment of wastewater contains alkanolamine (MEA, DEA and DIPA, respectively) [2][3][4]. However, some problems such as forming sludge during treatment and only applicable in the particular pH i.e.…”

Effluent containing high concentration of alkanolamine from a sweetening process of natural gas plant is commonly generated during maintaining, cleaning and scheduled inspection of the absorption and desorption column. The effluent is not readily biodegradable and cannot be treated in the conventional biological treatment. Advanced oxidation processes (AOPs) is a promising method for the treatment of recalcitrant organic contaminant. Most methods used are Fenton reagent, UV/Ozone and UV/H2O2. Based on the advantages of the UV/H2O2such as no formation of sludge during the treatment, high ability in production of hydroxyl radical and applicable in the wide range of pH, the UV/H2O2has been chosen to treat the effluent from refinery plant, which has high concentration of methyldietnaolamine (MDEA). The factors influencing in the degradation of refinery wastewater that contain MDEA were screened using response surface methodology (RSM). It was found that degradation process of the refinery effluent was highly dependent on oxidant concentration (H2O2) and initial pH. Temperature of oxidation process was found oppositely. Since the temperature gave insignificant effect on the TOC removal process, hence the independent factor temperature will be eliminated during the further optimization process condition of degradation. Thus, the optimization process condition of degradation will be more effective and simpler.

“…The Fenton' reagent in the AOPs was used to degrade MEA [10], DEA [11], N,N-diethyl-p-phenylenediamine [12] and DIPA [13]. Also, the use of UV/H 2 O 2 in the AOPs for degradation of MEA and MDEA [4,14] and ozonation for degradation of DEA [15] have been studied.…”

Methyldiethanolamine (MDEA) as an organic material is a hazardous contaminant in the aquatic environment because of its adverse effects on aquatic life, environment, and humans. In this study, a batch reactor of ultraviolet (UV) light and peroxydisulfate was performed to investigate the degradation of MDEA in aqueous media. The effect of different experimental parameters such as UV irradiation, peroxydisulfate concentration, MDEA concentration, temperature, and solution pH on removal of MDEA was evaluated precisely. No significant degradation was observed with a separate UV light. Adding peroxydisulfate to the solution increased the removal performance more than 75 %.
