Phosphorus as a diminishing resource, is an essential element for the growth of biota. However elevated concentrations in water imbalance ecosystem and cause eutrophication. To address both problems, two highly efficient biochars, namely La-OB CeLa-OB were synthesised by lanthanum cerium doping. The performance evaluated both, batch dynamic regimes with synthetic phosphate (PO43--P) solutions eutrophic lake water. PO43--P adsorption mechanisms investigated terms pH, kinetics, isotherms, activation energy, thermodynamics in-depth characterisation (XPS, FTIR, XRD, BET, pHpzc SEM-EDX); feasibility using biochar 'real life' was studied column filtration low high concentrations, along reusability/desorption toxicity trials environment. mechanistic study showed that biochars dominantly made inner-sphere complexes La Ce ligands (as monolayer), while outer-sphere complexation less common. exothermic process followed Elovich kinetic Langmuir isotherm models maximum capacity 112 mg/g 40 CeLa-OB. In reached 78 mg/g, metal leaching (0.08 mg/L) to Lepidium sativum germination detected. results indicated these especially could be used circular economy-based treatment.
