英文摘要	Heavy metal removal in waters is a serious environmental issues, in the present study, a new nanocomposite (0001-La(OH)(3)) was prepared by encapsulated nano-La(OH)(3) particles onto polymeric porous cationic exchanger 0001 for enhanced lead sequestration. The removal of lead ions onto D001-La(OH)(3) is pH-dependent process with the optimal sorption pH ranging from 4.5 to 5.8 and the resulting D001-La(OH)(3) exhibits strong sorption selectivity and superior sorption capacities (336 mg/g), which can be mainly ascribed to the formation of strong inner sphere complexation between nano-La(OH)3 and lead ions and high charged sulfonate group (SO3-H) diffusion enrichment effects towards lead ions: Moreover, D001-La(OH)3 also presents rapid sorption kinetics and efficient column applicability. Particularly, the used hybrid material can be readily regenerated by 0.5% HNO3 and 10% NaCl mixtures. All the results demonstrate that the new nanomaterial D001-La(OH)(3) is a promising candidate for lead sequestration enhancement.
