摘　　要：以二水合醋酸锌和浓氨水为原料,以海藻酸钠为表面活性剂,采用水热法制备纳米ZnO材料。透射电镜(TEM)和X射线衍射仪(XRD)研究表明,ZnO形貌为玉米穗状,宽度约为70nm,晶型为六方纤锌矿结构。以原子吸收光谱为检测手段,研究了纳米ZnO材料对Cu(Ⅱ)的吸附行为,结果表明,在pH值为6.8时,纳米ZnO材料对Cu(Ⅱ)的饱和吸附量为16.1mg/g,吸附过程具有Langmiur等温吸附特征。Using zinc acetate and concentrated ammonia as raw materials,sodium alginate as surfactant,zinc oxide materials were synthesized by the hydrothermal method. The transmission electron microscope（ TEM） study show that the morphology of sample is like corncob and the width is about 70 nm,and it exhibits haxagonal wurtzite structure. The adsorption behavior of Cu（Ⅱ） on ZnO was investigated by atomic absorption spectroscopy. The results show that the maximum adsorption capacity of ZnO nanoparticles is16. 1 mg/g. The adsorption process of ZnO particles is in accordance with the Langmuir model.
