摘要：
Co-pyrolysis of magnesite with food waste generated MgO hybrid biochar composite.MgO hybrid biochar showed a high phosphorus recovery capacity (523.9 mg/g).Phosphorus recovery was controlled by MgHPO4 formation and electrostatic attraction.MgO hybrid biochar recovered > 98% of P from solution and bio-liquid wastewater.Recovered phosphorus is a slow-release fertilizer available for agriculture use.
