Sediment is a critical component of aquatic ecosystems, that acts as natural sink for diverse pollutants such heavy metals and phosphorus (P). However, the current research on sediment remediation has predominantly focused single contaminants. In this study, novel composite material, calcium peroxide/lanthanum-loaded hydrochar (CaO2–LaHyd), was synthesised through hydrothermal carbonisation water purification sludge, followed by sequential loading lanthanum ions nano-calcium peroxide. The adsorption capacities CaO2–LaHyd P Pb were evaluated via experiments, their passivation mechanisms investigated capping simulations. Materials characterised using scanning electron microscopy, X-ray photoelectron spectroscopy, diffraction, energy-dispersive spectroscopy. Results indicated exhibited maximum 66.05 mg·g⁻¹ 230.41 Pb. simulated addition 5% significantly reduced phosphate concentrations in overlying water. slow release oxygen from peroxide improves redox conditions, suppresses endogenous release, decreases interstitial levels. Speciation analysis revealed promoted transformation into stable forms while reducing bioavailable fractions. Concurrently, it enhanced passivation, thereby mitigating leaching risks sediment.
