摘　　要：湿法炼锌过程会造成大量的冶炼废弃高硫渣,这些渣中含有大量的亲汞元素硫。基于以废治废的理念,采用高硫渣对烟气中的汞进行吸附,通过XRD等手段对制备材料的性能进行表征,分析其物理化学性质,并对吸附条件进行研究。结果表明,160℃下高硫渣对单质汞的吸附效率较好,达到了66.28%,而经过ZnO改性之后的高硫渣,其吸附效率在模拟烟气气氛以及不同的温度条件下均可以达到85%。Zinc hydrometallurgy process will cause a large amount of smelting waste high-sulfur slag,which contains a large amount of mercury-rich sulfur element.Based on concept of treating waste with waste,high-sulfur slag is used to adsorb mercury in flue gas,and performance of prepared material is characterized by XRD and other methods,physical and chemical properties are analyzed,and adsorption conditions are studied.The results show that high sulfur slag has good adsorption efficiency of 66.28%for elemental mercury at 160 ℃,while high sulfur slag modified by ZnO can reach 85% in simulated atmosphere and temperature conditions.
