Pb contamination in aquatic environments causes severe pollution;therefore,harmless absorbents are required.In this study,we report a novel synthesis of whitlockite(WH,Ca18Mg2(HPO4)2(PO4)12),which is the second most abundant biomineral in human bone,and its application as a high-performing Pb2+absorbent.Hydroxyapatite(HAP)and WH are prepared via a simple precipitation method.The Pb2+absorption performance and mechanism of the synthesized biominerals are investigated in aqueous solutions at neutral pH.The results demonstrate that WH exhibits an excellent Pb2+absorption capacity of 2339 mg g-1,which is 1.68 times higher than the recorded value for HAP.Furthermore,the absorbed Pb2+ions are recycled into high-purity Pbl2.This is employed as a precursor for the fabrication of perovskite solar cells(PSCs),resulting in a conversion efficiency of 19.00％comparable to that of commercial Pbl2 powder(99.99％purity).Our approach provides an efficient way to remove Pb2+ions from water and reuse them in the recycling of PSCs.
