英文摘要Recovery of phosphorus (P) from incinerated sewage sludge ash (ISSA) by biochar is an attractive solution for mitigating the P scarcity and transferring waste to resources. This work used Mg/Ca-modified biochars to take up P from the acid-extract from ISSA at low pH (<2), which simplified the previous P recycling process. The hypothesis is to produce a P-enriched post-sorption biochar that can be directly applied as a P fertilizer. Wastes of peanut shell and sugarcane bagasse were used to synthesize Mg/Ca-modified biochars at pyrolysis temperatures of 450 degrees C, 700 degrees C and 850 degrees C. Preliminary results indicated Mg-modified sugarcane bagasse biochar pyrolysed at 700 degrees C produced optimal P-absorption. This biochar was positively charged and had a high specific surface area (1440 m(2)/g), consistent with a layered porous structure. The optimal biochar showed rapid adsorption of P which could be described by the pseudosecond-order model. Successful adsorption of P from the acid-extract by the optimal biochar was mainly due to chemical precipitation and its adsorption capacity is 129.79 mg P/g biochar. (C) 2019 Elsevier Ltd.
