本文从上海某燃煤电厂采集了粉煤灰样品。进行了未燃碳测试、汞含量测定、SEM分析、比表面积、平均孔径和孔容测试等一系列实验，并实验研究了飞灰对烟气汞的吸附能力。结果表明，粒径大于100μm的粉煤灰吸附效率最高，为67.83%；粒径小于25μm的粉煤灰吸附效率最小，为13.67%。分析了相关机制。
In this paper, fly ash samples were collected from a coal-fired power in Shanghai. A series of experiments, including unburned carbon testing, mercury content measurement, SEM analysis, specific surface area, average pore size and pore volume test, were conducted, and the adsorption ability of the fly ash on the flue gas mercury was also experimentally studied. It has shown that fly ash with particle size bigger than 100µm is with the highest adsorption efficiency, 67.83%, and that fly ash with particle size smaller than 25µm is with the smallest adsorption efficiency, 13.67%. The relative mechanism was analyzed.
