The present study proposes an integrated system based on the synergetic action of solar photocatalytic oxidation with surface flow constructed wetlands for the purification of wastewater contaminated with pesticides. Experiments were conducted at pilot scale using simulated wastewater containing the herbicide clopyralid. Three photocatalytic methods under solar light were investigated: the phot...

Abstract The present study deals with the preparation of nanomagnetite (NM), potassium carrageenan (KC), and nanomagnetite/potassium bio-composite beads (NC). Characterization prepared solid materials using different physicochemical techniques such as X-ray diffraction analysis (XRD), thermogravimetric (TGA), scanning electron microscopy (SEM), transmission microscope (TEM), energy-disperse spe...

To establish an efficient oxidation process for carbofuran degradation, the effects of some operating parameters such as dosages of H(2)O(2), Fe(2+) and initial carbofuran concentrations were observed during carbofuran degradation by the ultrasound process, Fenton process and a combined ultrasound/Fenton process. The degradation kinetics of carbofuran was also examined based on the experimental...

This study presents a machine learning (ML)/artificial intelligence (AI)-based perspective to reliably predict and enhance the treatment efficiency of landfill leachate by classical-Fenton (c-Fenton) photo-Fenton (p-Fenton) processes. experiment also sought lower costs evaluating impact using different numbers UV-c (254 nm) lamps during p-Fenton processes, as well develop sustainable process de...

Photo-induced Advanced Oxidation Processes (AOPs) using H2O2 or S2O82? as radical precursors were assessed for the abatement of six different contaminants emerging concern (CECs). In order to increase efficiency these AOPs at a wider pH range, catechol organic functional compound was studied potential assistant in photo-driven iron-based processes. Different salinity regimes also (in terms Cl? ...

Herein, the recycled magnetite obtained from industrial ferrous scrap was used as an eco-friendly, sustainable iron source in photo-Fenton degradation of carbamazepine (CBZ), emerging contaminant aqueous environment. Citrate a robust chelating agent to trap and stabilize required for Fenton reaction. The results proved formation Fe(III)-citrate complex, followed by reduction Fe(II) harmless mol...

In the present work advanced oxidation process, photo-Fenton (UV/H2O2/Fe) system, for the treatment of wastewater contaminated with oil was investigated. The reaction was influenced by the input concentration of hydrogen peroxide H2O2, the initial amount of the iron catalyst Fe, pH, temperature and the concentration of oil in the wastewater. The removal efficiency for the system UV/ H2O2/Fe at ...
