Abstract

Newly few-layered boron nitride (BN-550) nanosheets were developed by a low-temperature synthesis method, which was used to rapidly and efficiently adsorb lead ions (Pb2+). The samples were characterized by using XRD, FT-IR, EELS, SEM, TEM, AFM and XPS, revealing that it possessed the large specific surface area (696m(2)g(-1)), ultrathin sheet structure (1.2nm thickness), and abundant chemical bonds as multiple adsorption sites. The adsorption properties showed that higher adsorption capacity (845mgg(-1)) for lead ions and less equilibrium time (15min) than many adsorbents reported at present. The adsorption kinetics and isotherms of BN-550 belonged to the pseudo-second-order model and Langmuir model, respectively. The easy recyclability and stability of BN-550 were verified by the experiments regeneration and pH. Interference experiments indicated that the adsorbents were strong affinity for Pb2+ under the interference of other heavy metal ions such as Ni2+, Cu2+, and Cd2+ ions (their adsorbing capacity individually are 201, 402, and 312mgg(-1)). The XPS and FT-IR analysis revealed that the excellent adsorption performances for Pb2+ attributed to the chemical binding reactions with the numerous surface functional groups, such as the strong B-O-Pb interactions and -NH2 Pb complex . The threshold value of Pb2+ removal on BN-550 nanosheets was 1080mLg(-1) when Pb2+ concentration was 50mgL(-1) in adsorption column. The unique characteristics render ultrathin nanosheets highly promising as an ideal candidate for the removal of lead ions.
