Adsorption isotherms of pure gases present in flue and natural gas including CO2, N2, CH4 and water were studied using prussian blues of chemical formula M3[Co(CN)6]2 (M = Cu, Ni, Mn). These materials adsorbed 8-12 wt % of CO2 at room temperature and 1 bar of pressure with heats of adsorption ranging from 6 to 16 kcal/mol.
