“…UV illumination in combination with Fenton's reagent demonstrated a pronouncedremoval effect, possibly due to the additional reaction intermediates, ˙OH radicals, generated by the UV illumination. These findings agree with previous studies mentioned in the literature [41]. Furthermore, to verify the role of Saccharum officinarum, treatmentusing UV/H2O2 at a dose of H2O2 of 400 mg/L is carried out.…”

“…This is because the generated ˙OH species are inadequate for treating the whole dye. Increasing the oxidation activity, under UV illumination, by reducing the starting pollutant load has previously been investigated in [41], where the authors applied Fenton's oxidation to treat benzimidazole. Although the oxidation varies for various concentrations, the same trend is observed in the high initial drop in concentration followed by a slower oxidation rate in all cases.…”

In the current investigation, elements extracted from Saccharum officinarum were identified as exporters of Fenton catalysts. Saccharum officinarum was soaked in an alkali prior to acidic treatment and then subjected to pyrolysis for elemental recovery. X-ray diffraction (XRD) and scanning electron microscopy (SEM) augmented with energy-dispersive X-ray spectroscopy (EDX) were used to identify the prepared catalyst. The material was combined with hydrogen peroxide, which led to Fenton’s reaction. Then, the modified Fenton system was applied to eliminate the textile dye, named Bismarck Brown Azo dye, contaminating the aqueous effluent. Response surface methodological model (RSM) analysis was used to identify the most effective operational parameters, and the model set the optimized values as 39 and 401 mg/L for Saccharum officinarum and H2O2 doses, respectively, at pH 2.9. The maximum Bismarck Brown Azo dye removal achieved was 85%. Increasing the temperature to 60 °C improved the dye oxidation efficiency. However, the dye treatment efficacy was reduced when the dye loading increased. Additionally, the kinetic rate order was investigated and the system was fitted to second-order rate reaction kinetics. The thermodynamic variables show that the reaction is endothermic and non-spontaneous.
