▎ 摘  要

NOVELTY - A nanomaterial comprises nanoparticle core, polydopamine coating layer and phosphoramidate compound modified layer. USE - Nanomaterial used for selectively adsorbing lead ion in water treatment application (all claimed). ADVANTAGE - The nanomaterial has selective adsorption capacity for lead ions in water. The method is simple, and economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of nanomaterial, which involves (S1) dispersing nanoparticle in a solvent, adding dopamine to react, washing, drying, and (S2) dispersing the nanoparticle in solvent, adding phosphoramidate compound to react, washing and drying.
