对污泥吸附剂的吸附机理进行了探讨，认为在没有水蒸气存在的条件下，吸附以物理吸附为主，SO_2不能被催化氧化为SO_3；

It was discussed about adsorption mechanism of sludge adsorbents, and was considered that in the condition of no water, physical adsorption was primary, SO_2 was not catalyzed and oxidized into SO_3;

利用红外光谱仪（IR）、智能重量分析仪（IGA）等表征手段对吸附剂的物理结构和化学组成进行表征。

The structure, composition and framework of the matrix were characterized by infrared spectrometer (IR) and intelligent gravitation analyzer (IGA).
