In this work, the decomposition of bisphenol S (BPS) by biochar derived from banana peel (BPB) promoted copper phosphide (Cu3P) was examined. Different materials with Cu3P loadings 0.25 to 4.00 wt.% on were synthesized, characterized using Brunauer–Emmett–Teller (BET) method, X-ray diffraction (XRD) and a scanning electron microscope (SEM) equipped an energy dispersive spectrometer (EDS), evaluated. Nearly all synthesized exhibited low moderate adsorption capacity, attributable their limited surface area (<3.1 m2/g). However, in presence sodium persulfate (SPS), 2%Cu3P/ΒPB/SPS system capable removing 90% 500 μg/L BPS less than 10 min. The system’s performance enhanced under inherent pH, reaction rate followed pseudo-first-order kinetics respect concentrations. Interestingly, 250 mg/L chloride had negligible effect, while inhibition observed bicarbonates humic acid. contrast, significant retardation experiments performed real matrices, such as secondary effluent (WW) bottled water (BW). According scavenging experiments, both radical non-radical mechanisms participated degradation. Four transformation products identified UHPLC/TOF-MS negative ionization mode, two them having higher molecular weights BPS, other TBPs involved ring-opening reaction, pathway proposed.

This study examines the degradation of sulfamethoxazole (SMX) in water using photo-Fenton process, focusing on dissolved oxygen (DO) dynamics, organic matter mineralization, and quality improvement. The results show that SMX follows a rapid kinetic pattern, achieving complete removal within 30 min. However, total carbon reduction occurs more gradually, indicating persistence intermediates before full mineralization into CO2 H2O. DO evolution biphasic trend: an initial decline due to oxidative consumption, followed by increase H2O2 decomposition O2. Initially, at [H2O2]0 ≥ 3.0 mM, sharply increases, while [Fe(II)]0 = 5.0 mg/L, reaches minimum 0.3 mg/L higher reactive species (ROS) production. Water parameters such as color, turbidity, aromaticity were also monitored. Aromaticity significantly decreases min, confirming ring cleavage. Color turbidity initially intensify intermediate formation but later decrease progresses. Optimal conditions (1 mol SMX: 10 H2O2: 0.05 Fe(II)) ensure efficient with minimal depletion without excessive scavenging effects. These findings confirm process effectively removes improving quality, making it sustainable alternative for pharmaceutical wastewater treatment.
