The use of hydrogen peroxide (produced in situ or ex situ) as the main agent oxidative processes environmental pollutant removal is widely studied. degradation water pollutants, such dyes, pharmaceuticals, cosmetics, petroleum derivatives, and even pathogens, has been successfully obtained by different techniques. This review gives an overview more recent methods developed to apply mediated H2O2 other reactive oxygen species (ROS) catalysis, with particular attention strategies (Fenton-like Bio-Fenton, photo- electro-catalysis) materials employed. A wide discussion about characteristics specifically studied for activation, well their chemical composition morphology, was carried out. Moreover, interesting generation enzymes were also presented efficiency applicability compared Fenton electro-Fenton discussed above. Bio-Fenton bi-enzymatic ROS seems be attractive scalable, although not yet applied full-scale plants. critical feasibility, criticalities, perspectives all considered completes this review.

The adsorption property of the costless green cellulose acetate (CA) was boosted by dual modifications: inner modification incorporating carboxylated graphene oxide (COOH-GO) into CA spheres and outer surface COOH-GO@CA iminodiacetic acid (IDA) for removing Pb(II). experiments Pb(II) proceeded in a batch mode to evaluate COOH-GO@CA@IDA spheres. maximal capacity attained 613.30 mg/g within 90 min at pH = 5. removal reached its equilibrium 20 min, % almost 100% after 30 low concentration. mechanism proposed according kinetics isotherms studies; addition, zeta potential (ZP) measurements X-ray Photoelectron Spectroscopy (XPS) analysis defined pathways. By comparing XPS spectra authentic used COOH-GO@CA@IDA, it deduced that contributed chemical pathways are Lewis acid-base, precipitation, complexation. demonstrated electrostatic interaction participation adsorbing cationic species onto negatively charged (ZP 14.2 mV 5). unique channel-like pores suggested pore-filling promising results superb recyclability character enable extend bench scale industrial scale.

In this work, cotton stalks (Gossypium barbadense) and date palm stones (Phoenix dactylifera) have been used as biosorbents to remove cadmium; Cd(II), lead; Pb(II), zinc; Zn(II) from mono- multi-solutions. Each biosorbent was characterized using SEM-EDX, FT-IR. The findings showed that pH, dose, contact time, metal concentration, particle size affect the treatment process. adsorption pattern Pb(II) > Cd(II) for both biosorbents. performance of higher than stones. fitted maximum uptake capacities; q

This study explores the adsorption of doxycycline (DOX) from aqueous solutions onto biochar derived banana peel, which was prepared using a potassium hydroxide activation method (KOH-BPB). The properties were characterized based on morphology, surface area (SBET 710.241 m<sup>2</sup> g<sup>-1</sup>), functional groups, and charge (pHPZC = 7.7). Parameters, including initial pH, DOX concentration, ionic strength, that influenced capacity KOH-BPB examined. Adsorption equilibrium assessed through four isothermal models: Langmuir, Freundlich, Temkin, Dubinin-Radushkevich models. obtained data most compatible with Langmuir model (R<sup>2</sup> 0.9879). has maximum absorption 121.95 mg g<sup>-1</sup> exceeds many comparable absorbents. removal 96.7% at pH 6, concentration 20 L<sup>-1</sup>, dose 1.0 g L<sup>-1</sup>. These findings reveal peel effectively removes antibiotic residues water. provides potential, low-cost, environmentally friendly adsorbent.
