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.
