According to the analysis on surface physical and chemical characteristics, a mechanism was concluded: Modified by microwave, functional groups begin to dissociate, alkalescency is enhanced, and surface oxygen content is reduced; the amount of active sites produced by dissociation of oxygen-containing groups increased, so did the pyrrole-N groups. Apparently, the activated energy of SO_(2) adsorption decreased.

应用正交实验研究了微波功率、辐照时间、活性炭粒径对微波改性活性炭脱硫效果的影响，显示微波功率是决定改性活性炭502吸附容量的关键因素，微波功率的增加可以加强改性活性炭的502吸附能力，辐照时间对活性炭改性的影响在4一smin内突出，活性炭粒径越小，改性效果越好，对50：吸附容量也越大。
