Synthesis of Bi-Functional Biochar Utilizing Incinerated Sewage Sludge Ash and Biomass: Improved Nutrient Release and Heavy Metal Adsorption Efficiency

Published: Jan. 1, 2025

Phosphorus (P) is vital for plant growth and abundantly found in incinerated sewage sludge ash (ISSA). However, utilizing this P-rich ISSA efficiently as fertilizer remains a key challenge. This study first successfully synthesized bi-functional biochar-based using acid-extracted shrimp shell through pyrolysis. We systematically examined how impregnation methods, pyrolysis temperatures, biomass types influenced available phosphorus (AP) release, with further optimization Cu(II) adsorption performance mechanism. AP release results indicated that the pre-pyrolysis impregnated biochar prepared at 350 °C (Im-SS350-pre) had maximum (51.68 mg P/g). demonstrated Im-SS350-pre achieved capacity of 66.86 mg/g, due to its highly effective reactive sites. was three times high produced without (25.08 mg/g). For XRD analysis confirmed acid leaching broke metal-P bonds, releasing Ca‒P Mg‒P, while promoted formation phosphate concentration. adsorption, FTIR, XRD, XPS analyses identified mechanisms such coordination, co-precipitation, functional group complexation, Cu‒π interactions. highlights dual functionality providing promising approach recovery copper remediation biomass.
