摘　　要： 采用固定床动态吸附法研究赤泥对硫酸雾的吸附效果,探讨了赤泥不同煅烧温度、煅烧时间以及填料孔隙率对硫酸雾吸附效果的影响.结果表明,赤泥对硫酸雾具有较好的去除效果.当煅烧温度为750℃、煅烧时间为5 h、孔隙率为26%时,赤泥对硫酸雾的去除率最高,能达到95%以上.运用扫描电镜、X-射线衍射、比表面积测定等方法分析了赤泥的结构特征和成分组成,证明赤泥具有较好的吸附性能. In this paper,the dynamic sorption of sulfuric acid mist from lead-acid battery plants by red mud was studied. The effect of sintering temperature,sintering time and sorbent porosity of red mud on H2SO4 mist removal efficiency was investigated. It was found that the sintered sorbents exhibit higher removal capacity for sulfuric acid mist when compared with that of raw red mud. The removal efficiency of sulfuric acid mist can be higher than 95%with the sintering temperature of 750 ℃,sintering time of 5 h and sorbent porosity of 26%. The physical and chemical properties of sorbents were characterized through scanning electron microscopy and X-ray diffraction analyses.
