摘要：

The porous AlOOH is synthesized via a simple hydrothermal reaction for the first time, and AlOOH nanospindles exhibited a significantly adsorption properties toward lead ion (Pb). The microstructure and morphology of the AlOOH nanospindles were investigated by XRD, SEM, TEM and BET. The effect of reaction conditions on the micromorphology were investigatived with regard to reaction temperature, amount of reactants and surfactants. The maximum adsorption capacity of AlOOH nanospindles for Pb(II) is 53.04 mg g(?1) at 313 K, and the adsorption process is endothermic. The adsorption of AlOOH nanospindles and Pb(II) is mainly attributed to the p-p stacking interactions and electrostatic interactions between negative charge on the surface of AlOOH nanospindles and Pb(II). The AlOOH nanospindles adsorbent having excellent adsorption properties and good recyclability of Pb(II). Therefore, AlOOH nanospindles is a potential adsorbent for water treatment in the future.
