Optimum levels of initial pH, temperature, hydrogen peroxide concentration, initial dyestuff concentration, and iron concentration were determined. Initial pH, Fe2+ concentration, temperature, and initial Novacron Black concentration are the most effective experimental parameters in the decolorization of Novacron Black with Fenton and photo-Fenton processes. While the Novacron Black concentration was 200 mg/L, the H2O2 concentration was 100 mg/L, the initial solution pH was 3, and the temperature was 20 °C, a decolorization efficiency of 82.1% was obtained in the Fenton process at a concentration of 5 mg/L Fe2+, while in the photo-Fenton process at a 2 mg/L Fe2+ concentration, a 94.6% decolorization efficiency was obtained. Upon decolorization of Novacron Black, the photo-Fenton process had a higher removal efficiency than the Fenton process, even at low iron concentrations. From data obtained at various concentrations of initial Novacron Black, the non-linear method was used to determine the decolorization kinetics of Novacron Black. Finally, an economic analysis was carried out to compare the differences in operating costs between Fenton and photo-Fenton processes.Web of Science Decolorization of reactive azo dye from aqueous solutions with Fenton oxidation process: effect of system parameters and kinetic study(2019.01.01) Degermenci, N; Degermenci, GD; Ulu, HBWeb of Science Investigation ff kinetic and removal of organic matter from cosmetic wastewaters by fenton process(2017.01.01) Bayhan, YK; Degermenci, GDWeb of Science Removal of Phosphate from Aqueous Solution Using Anion Exchange Resin: Equilibrium Isotherms and Kinetics(2023.01.01) Korkmaz, C; Degermenci, GD; Degermenci, NPublication Removal of reactive azo dye using platinum-coated titanium electrodes with the electro-oxidation process(2021-04-01) Değermenci G.D.; Degermenci, GDThe removal of Drimaren Orange HF 2GL (DOHF2GL) azo dye from aqueous solutions was researched using platinum-coated titanium electrodes with the electro-oxidation process. The effects of electrolyte type, NaCl concentration, current density, initial dye concentration, pH, and solution temperature on dye removal were investigated. The maximum removal efficiency was determined as 98.7% at the end of 120 min for electrolyte concentration 4 g/L NaCl, current density 1.74 mA/ cm2, temperature 20°C, pH 7, and dye concentration of 100 mg/L. When NaCl was used as an electrolyte, there was lower energy consumption and higher dye removal compared to NaNO3 and Na2 SO4 . With the increase in NaCl concentration, the cell potential reduced, and the treatment efficiency was determined to increase. The current density was the most important param-eter affecting dye removal rate and energy consumption was determined to be largely linked to the current density applied. The dye removal efficiencies increased with the applied current density and electrolyte concentration and decreased with the increase in initial dye concentration. Experimental data under different reaction conditions were used to determine that the dye removal kinetics followed pseudo-first-order kinetics. Fourier transform infrared spectroscopy (FTIR) studies were performed to assess the degradation of dye with the electro-oxidation process.Web of Science Removal of reactive azo dye using platinum-coated titanium electrodes with the electro-oxidation process(2021.01.01) Degermenci, GD
