中文摘要：

分别利用水中DO氧化硝酸锰和硝酸溶解的锰尾矿生成锰氧化物，并直接对水中的Tl^＋进行吸附，探究了生成锰氧化物的投加量、DH、时间、初始含量、双氧水、共存Ca^2＋、Mg^2＋及重金属离子对去除Tl^＋效能的影响。结果表明，在碱性条件下，直接氧化硝酸锰生成锰氧化物对水中Tl^＋具有很好的去除效能，室温下反应10min，初始质量浓度为10mg／L的Tl^＋去除率可达到98．5％。水中高含量Ca^2＋、Mg^2＋会降低Tl^＋的去除效果，Pb^2＋、Cd^2＋、Cr^2＋对Tl^＋的去除效能影响不明显。吸附过程可用Freundlich吸附等温模型描述。利用该方法对实际废水进行处理，铊的去除率达95．0％；在少量双氧水作用下，直接氧化锰尾矿生成锰氧化物，对多个实际废水处理效果显著，去除率可高达96．9％。

英文摘要：

Manganese oxide was generated by manganese nitrate and manganese tailings dissolved in nitric acid respectively, which were oxidized by the dissolved oxygen. Manganese oxide was used for adsorption Tl^＋ in the water directly. The effect of the dosage of manganese oxide generated, pH, adsorption time, initial content and hydrogen peroxide, Ca^2＋, Mg^2＋ and heavy metal ions coexisted in water were explored on Tl^＋ removal. Under alkaline conditions, the manganese oxide generated by the manganese nitrate oxidized directly had the perfect efficiency on the TP removal, 10 mg/L of Tl^＋ was reduced by 98.5% after reacting for 10 min at room temperature, Tl^＋ removal was reduced by high content of Ca^2＋, Mg^2＋ in water, while Pb^2＋ and Cd^2＋, Cr^3＋, had no significant effect on the Tl^＋ removal. The adsorptions were fitted well by the Freundlich isothermal. Thallium in wastewater was reduced by 95.0%. Manganese oxide generated by manganese tailings oxidized directly had remarkable treatment for multiple wastewater with a small amount peroxide, removal rate could reach 96.9%.
