Water pollution has emerged as a critical global challenge, particularly the contamination of water bodies with persistent organic pollutants such Bisphenol S (BPS), known endocrine disruptor. This study presents synthesis and application eco-friendly bio-based coconut shell magnetic biochar (CSMB) for efficient sequestration BPS from aqueous environments. Utilizing pyrolysis co-precipitation techniques, was characterized through various methods including surface chemistry (pHpzc), electron dispersive X-ray analysis (EDX), Brunauer-Emmett-Teller (BET) N2 adsorption-desorption, scanning microscopy (SEM), vibrating sample magnetometer (VSM), Fourier transform infrared spectroscopy (FTIR). SEM revealed porous structure high area, while FTIR confirmed presence functional groups essential adsorption. diffraction (XRD) VSM successfully incorporated nanoparticles, enhancing separation process post-adsorption. The CSMB demonstrated significant area 373 m2 g−1, outperforming regular (CSB), adsorption capacity 43.5 mg/g compared to 26.7 CSB. Batch tests assessed impact operational factors initial concentration (8–150 ppm), contact time (30–150 min), temperature (298.15, 318.15, 338.15 K), pH (3–11), dosage (0.1–0.9 g). results indicated optimal at 6 maximum 52.3 mg/g. Kinetic studies that pseudo-second-order model best described process, Langmuir isotherm provided an excellent fit data. reusability validated over five cycles, decreasing slightly approximately 41 mg/g, making it sustainable effective adsorbent treatment.

Abstract The valorisation of waste from rose-based industrial products produces value-added substances and paves the way for advanced composites. rose generated essential oil industry Taif ( Rosa damascena trigintipetala Dieck) is significant, its management or disposal a source concern. In this study, it was valorised to produce nanomaterial. synthesis biochar nanoparticles via high-energy ball milling has gained tremendous research interest in recent times because low cost eco-friendliness. Ball solvent-free technology with strong potential volatilisation eco-sustainability through production engineered nanoparticles. Different samples were produced characterised harness synergistic combination milling. They prepared at constant pyrolysis temperature 300 °C by varying 2 h, 5 10 h. characterisation results showed that confirms high content carbon, minerals, graphitic structure, novel morphology chemical characteristics attached surface controlled different durations. These properties further enhanced porosity, area, functional groups, visible light absorption, crystallinity, carbon content, these accompanied reduction particle size mineral impurities. can be an important tool, promising composites water purification energy harvesting.

Large quantities of date palm frond waste generated from the pruning process are accumulated or burned in burn barrels, harming environment and having very little economic value. However, because lack data revealing characteristic magnetic properties biochar derived fronds, further research on low-cost sustainable strategies could offer a new composite material serve to extend way for novel applications. In this study, we prepared fronds via pyrolysis under limited-oxygen atmosphere at lower temperature 300 °C 2 h. We introduced facile strategy production with various doses annealed steel sludge ball milling. Various amounts (5%, 15%, 25% w) were added biochar, obtained product was fabricated by The physicochemical characteristics subsequently analyzed using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy, UV-vis spectroscopy. Our findings showed that milling method is successful step producing possessing rough packed pores, as shown SEM. XRD patterns assumed existence phases iron oxide (magnetite (Fe 3 O 4 ), hematite (α-Fe maghemite (γ-Fe ) different peaks. FTIR outputs exhibited abundant presence oxygen-containing functional groups (- COOH -OH) surface material, which help create chemically reactive sites adsorb potential surrounding species.
