在干法室温常压状态下,利用滚压振动磨大批量制备尺度在50~80 nm的铝纳米颗粒.铝纳米颗粒在超声波作用下发生水解反应、经干燥、焙烧后制备出具有纳米结构的介孔γ-Al2 O3(比表面积高达406．9 m2/g).采用 X 射线衍射仪(XRD)、傅里叶变换红外光谱(FT-IR)、场发射扫描电子显微镜(SEM)、透射电子显微镜(TEM)和比表面测定(BET)等技术对介孔纳米γ-Al2 O3样品进行表征.并取0．2 g 不同条件下制备的介孔纳米γ-Al2 O3,考察其对Cl－的吸附性能.实验结果表明,所制备的介孔纳米γ-Al2 O3具有高比表面积、孔径大小均匀和高温稳定性.在焙烧温度为400℃、保温4 h 的条件下制备的介孔纳米γ-Al2 O3对 Cl－的吸附效率最高,对 Cl－的去除率为14．03％.
