Abstract
The article presents the results of the development of new composite materials obtained from coal fly ash (CFA) by the Fusion method.
The composite materials are doped with silver nanoparticles and characterized using advanced characterization methods, namely XRD, SEM-EDS, XRF. In the course of obtaining synthetic zeolites based on CFA, structural modification was carried out to quickly bind zeolites with mercury when it was removed from the aqueous medium and improve the physicochemical properties. The synthesized nanocomposites were used to remove Hg from aqueous solutions with different pH. It was found that the equilibrium of the adsorption capacity for synthetic zeolites occurs after about 2 weeks, while for the original CFA it is reached within a month. Preliminary results show a significantly high removal of mercury from the solution – from 80 to 90% of mercury ions.
