| 英文摘要 | Comprehensive utilization of phosphorus from spent LiFePO4 (LFP) battery has aroused considerable interest aiming to enhance the economic profit of recycling this type of low value-added battery. In the current study, a green and novel process was developed to recover phosphorus from spent LFP battery, which was further directly converted into phosphorus grafted slow-release fertilizer (P-SRF) with acid-resistance. Meanwhile, Li was simultaneously recovered. Effect of several parameters on the leaching efficiency of P was investigated, and the properties of P-SRF in acid and neutral conditions were clarified. In the whole process, the recovery efficiencies of Li and P were more than 99.5%, and furthermore, the synthesized P-SRF had high water-absorbing capacity and low release rate in both acid and neutral conditions. Mechanism study indicated phosphorus was recovered in the form of HPO42-/H2PO4- from spent LFP battery. HPO42-/H2PO4- reduced the activation energy of the condensation reaction between urea and acrylic acid to accelerate the reaction. Meanwhile, the low release rate of P-SRF in low pH was ascribed to the buffering effects of HPO42-/H2PO4- . Furthermore, pot experiments showed P-SRF effectively promoted the growth of maize. This study provided a profitable approach for high value-added recovery of spent LFP battery, and the recovered hydrophosphate could be further transferred into P-SRF with considerable acid-resistance, which has potential application in acid soil, horticulture and slope treatment. |
