Method for preparation of mesoporous silica form from power plant fly ash and carbon dioxide sorbents or rare earth metals ion collector based on mesoporous silica form prepared by the method

摘要

A method for manufacturing mesoporous silica foam using fly ash from a thermal power plant and a carbon dioxide adsorbent or rare earth metal ion recovery agent comprising the silica foam prepared according to the method, wherein the manufacturing method uses inorganic acid, the surface area, diameter and volume of the pores A mesoporous silica foam having excellent remarkability can be produced, and by using this, a carbon dioxide adsorbent having an excellent adsorption rate and a rare earth metal ion recovery agent having an excellent recovery rate can be produced.
