6.6 Further Directions
In our group, research and development of novel sorbents are taking directions
for mercury removal from flue gases of coal-fired power plant. Large mercury
adsorption capacity, effective capture, regenerability, and recyclability are a
few features to be considered to reduce mercury emission, control cost, and
recover mercury from coal-burning processes. The preliminary results showed
promising research direction of zeolite-based magnetic sorbents. The research
results will be published separately.
The mesoporous silica coating on magnetic particles has a well-characterized
surface morphology and can be modified to a wide range of functionality owing
to the presence of active hydroxyl groups. For example, the surface can be tuned
