“…Understanding the function of the oxidation processes that were indirectly generated during the treatment is one of the most critical aspects of explaining the high efficiencies attained by EOPs in the removal of EDCs. Indirect oxidation is the oxidation of EDCs via a chemical reaction with oxidants such as * OH, * CI, * SO4 -, O3, H2O2, and peroxosulphates formed in wastewater based on the composition of the electrolyte and electrode materials [39,40].…”

In this study, the treatment performance of the process in the removal of Endocrine Disrupting Compounds (EDCs) from domestic wastewater by a laboratory-scale electrooxidation process using Ti/IrO₂/RuO₂ electrodes as an anode was evaluated using response surface method (RSM). The effect of pH, current density, and flow rate on the electrochemical treatment of 17α-ethinylestradiol, β-estradiol, triclosan, and estrone, which are often present in wastewater, has been studied. Using Box-Behnken Design (BBD), the parameters influencing the removal efficiencies were optimized for the Electrooxidation process (EOP), and the models created essential second-order quadratic models for the EOP process. The Response Surface Method yielded results that reasonably agreed with the measured values. The maximum removals of triclosan, 17α-ethinylestradiol, and β-estradiol were attained at 92,90%, 97,76%, and 95,36% respectively, under experimental conditions optimized pH= 3,68, current density= 20 A and flow rate= 8,83 mL/min for EOP. Removal efficiencies have achieved their maximum levels at low pH, high current density, and low flow rate. At the same time, the electrooxidation method could not completely remove the estrone.

In this paper, green nanocomposites based on biomass and superparamagnetic nanoparticles were synthesized and used as adsorbents to remove methylene blue (MB) from water with magnetic separation. The adsorbents were synthesized through the wet co-precipitation technique, in which iron-oxide nanoparticles coated the cores based on coffee, cellulose, and red volcanic algae waste. The procedure resulted in materials that could be easily separated from aqueous solutions with magnets. The morphology and chemical composition of the nanocomposites were characterized by SEM, FT-IR, and XPS methods. The adsorption studies of MB removal with UV-vis spectrometry showed that the adsorption performance of the prepared materials strongly depended on their morphology and the type of the organic adsorbent. The adsorption studies presented the highest effectiveness in neutral pH with only a slight effect on ionic strength. The MB removal undergoes pseudo-second kinetics for all adsorbents. The maximal adsorption capacity for the coffee@Fe3O4–2, cellulose@Fe3O4–1, and algae@Fe3O4–1 is 38.23 mg g−1, 41.61 mg g−1, and 48.41 mg g−1, respectively. The mechanism of MB adsorption follows the Langmuir model using coffee@Fe3O4 and cellulose@Fe3O4, while for algae@Fe3O4 the process fits to the Redlich-Peterson model. The removal efficiency analysis based on UV-vis adsorption spectra revealed that the adsorption effectiveness of the nanocomposites increased as follows: coffee@Fe3O4–2 > cellulose@Fe3O4–1 > algae@Fe3O4–1, demonstrating an MB removal efficiency of up to 90%.
