“…These values compared well with the k ms values in the current investigation. Due to variations in the experimental procedures used by Albarrán and Mendoza [25], there is a slight discrepancy between the values found in the literature and the values acquired in this work. Additionally, Ghaly et al [26] found that the pseudo-first-order rate constants (k ms ) of chlorophenol with (OH • ) radicals were 0.15 in another scenario.…”

Due to their high toxicity, propensity for cancer, teratogenicity, mutagenicity, and genotoxicity, hazardous water-soluble phenolic compounds must be controlled immediately. In this study, a model was created to simulate the degradation of harmful recalcitrant organic compounds in a combined chemical and biological treatment system. The parameter estimations with inhibition coefficient (Haldane model) and without inhibition coefficient (Michaelis-Menten model) were assessed over a wide range of initial concentrations using the Monod-like model. The kinetic parameters were optimized using AQUASIM 2.0 software. At a 50 mgL−1 feed concentration of 4-chlorophenol, removal efficiencies of more than 98% were attained under these circumstances. The primary kinetic parameters were identified and their values models were validated using the fitted parameter values that reached a good degree of agreement (R2 = 0.998). We may better comprehend and make use of the complex phenolic compounds’ biodegradation processes, such as progress optimization and scale-up, by understanding the mechanisms of substrate interaction and the new kinetic models that have been provided in this work.

“…Glaze et al [98] made one of the earliest references to AOPs as processes involving the creation of hydroxyl radicals in sufficient quantity to effect water purification. Since the 1990s, the definition and development of AOPs have grown to encompass a number of ways for producing hydroxyl radicals and other reactive oxygen species, such as superoxide anion radicals, H [105,106], nonthermal plasmas [107], sonolysis [103,[108][109][110], H 2 O 2 /UV/ US [110], photocatalysis [108], radiolysis [111], and supercritical water oxidation processes [112,113].…”

Nowadays, increased human activity, industrialization, and urbanization result in the production of enormous quantities of wastewater. Generally, physicochemical and biological methods are employed to treat industrial effluent and wastewater and have demonstrated high efficacy in removing pollutants. However, some industrial effluent and wastewater contain contaminants that are extremely difficult to remove using standard physicochemical and biological processes. Previously, electrochemical and hybrid advanced oxidation processes (AOP) were considered a viable and promising alternative for achieving an adequate effluent treatment strategy in such instances. These processes rely on the production of hydroxyl radicals, which are highly reactive oxidants that efficiently break down contaminants found in wastewater and industrial effluent. This review focuses on the removal of contaminants from industrial effluents and wastewater through the integration of electrochemical and advanced oxidation techniques. These processes include electrooxidation, electrocoagulation/electroflocculation, electroflotation, photo-Fenton, ozone-photo-Fenton, sono-photo-Fenton, photo-electro-Fenton, ozone/electrocoagulation, sono-electrocoagulation, and peroxi/photo/electrocoagulation. The data acquired from over 150 published articles, most of which were laboratory experiments, demonstrated that the hybrid process is more effective in removing contaminants from industrial effluent and wastewater than standalone processes.

Some scientific studies have been conducted on the degradation of CBs through γ-irradiation [ 20 , 21 , 22 , 23 ]. In the study of [ 23 ] TCB has been irradiated in the transformer oil without any additive and >99 % conversion of TCB has been achieved.…”

“…Some kinetic properties of TCB degradation in deoxygenated 2-propanol and the conversion pathway results have been reported [ 21 ]. The degradation of 1,3-DCB was investigated in water-based solutions in the absence of oxygen, with the addition of N 2 O or N 2 O along with potassium ferrocyanide, K 3 Fe(CN) 6 , as described in the study [ 20 ]. Reported that, 1,3-DCB's degradation is dependent on the absorbed dose.…”
