摘　　要：探究不同形貌ZnO纳米材料对水中F-吸附性能。合成三种不同形貌的氧化锌纳米材料,并以这些材料作为吸附剂,探究F-的初始浓度、体系pH值、吸附时间和吸附温度四个因素对吸附效果的影响。结果表明:F-初始质量浓度为60 mg/L,pH值为6,吸附时间为30 min,吸附温度为30℃时氧化锌纳米立方体的吸附容量最高,达到137.4 mg/g;氧化锌纳米立方体的比表面积高于纳米网和纳米棒,其吸附容量高于氧化锌纳米网和氧化锌纳米棒的吸附容量。氧化锌纳米立方体材料的吸附效果具有更大的潜在应用价值。The adsorption properties of zinc oxide nano materials with different morphologies for F-in water were investigated.Three kinds of ZnO nano materials with different morphologies were synthesized and used as adsorbents to explore the effects of initial concentration of F-,system pH,adsorption time and adsorption temperature on the adsorption effect.The results show that when the initial concentration of F-is 60 mg/L,pH is 6,adsorption time is 30 min and adsorption temperature is 30℃,the adsorption capacity of zinc oxide nano cube is the highest,up to 137.4 mg/g.The specific surface area of zinc oxide nano cube is higher than that of nanomesh and nanorod,and its adsorption capacity is higher than that of zinc oxide nanomesh and zinc oxide nanorod.The adsorption effect of ZnO nano cubic materials has greater potential application value.
