摘　　要：研究了碳纳米管对水溶液中锌离子的吸附去除性能。结果表明:纯化的碳纳米管对锌离子的去除效果明显高于未纯化的碳纳米管,在25 mL、50 mg/L的锌离子溶液中当其用量为0.1 g时,纯化的碳纳米管锌离子的吸附去除率达94.8%;吸附60 min达到平衡;在中性和弱碱性溶液中的去除率大于酸性溶液。The carbon nanotubes （CNT） adsorption removal performance for Zn^2＋ from aqueous solution was studied. The results show that the removing effect of the purified CNT for Zn^2＋ is much better than that of the as-received ones. The 94.8% of Zn^2＋ can be adsorbed out from 25 mL, 50 mg/L, Zn^2＋ aqueous solution by adding a dose of 0.1 g purified CNT. The adsorption for Zn^2＋ reaches equilibration by 60 minutes. A little more adsorption can be obtained in neutral and weakly alkaline solution than in acid solution.
