Phosphate removal plays a pivotal role in alleviating eutrophication and maintaining water quality. Cerium (Ce) demonstrates considerable promise phosphate removal, attributed to its strong affinity for ions. This study provides dual utilization strategy synthesizing Fe2O3- CeCO3OH-decorated hydrophilic porous biochar (Fe/Ce@HPBC), designed recovery from eutrophic waters followed by application as slow-release fertilizer. Fe/Ce@HPBC possessed excellent adsorption quantity, achieving maximum uptake of 203.88 mg/g accordance with the Sips model. Furthermore, experiment demonstrated that used fertilizer after could sustainably release 39.8% content within 28 days. Fe/Ce@HPBC-P also significantly increase effective phosphorus soil 65.51% promote maize seedlings 70.36%. Mechanistic investigation revealed outstanding was formation inner-sphere complexation through ligand exchange between Ce(HCO3)2+/Ce–OH, addition electrostatic attraction caused enhanced surface protonation. Overall, this contributes advancement techniques promotes development sustainable agriculture presenting an mitigating eutrophication.

Abstract To effectively remove lead (Pb(II)) and bisphenol A (BPA) from wastewater, polyvinyl chloride modified magnetic hydrochar (PVC-AMHC) was synthesized through co-hydrothermal carbonization of corn straw, subsequently activated using NaOH. Characterization demonstrated that both PVC NaOH activation increased the content oxygen-containing functional groups, Fe 3 O 4 successfully loaded onto material surface. Furthermore, PVC-AMHC displayed remarkable uptake capacity with maximum amount Pb(II) (217.53 mg/g) BPA (185.53 at 130 30 min, respectively, under a wide pH range. Additionally, possessed high tolerance to different interference cations maintained excellent adsorption performance during four regeneration cycles. The thermodynamic analysis suggested absorption processes by PVC-MHC were spontaneous (-Δ G 0 ) an endothermic characteristic (+Δ H ). Adsorption mechanisms on included complexation, electrostatic attraction, pore filling, those mainly associated hydrogen bonding filling. In conclusion, environmentally friendly adsorbent simultaneous removal wastewater. Graphical
