Biofunctional Characteristics of Lignite Fly Ash Modified ...

2. Materials and Methods. Both humic substances and fly ash were extracted from the Greek peaty lignite of the Megalopolis Basin, Greece. The selection of lignite was based on the rich content of humic substances in the particular lignite field [7, 8, 17].Fly ash is a by-product during lignite combustion in Megalopolis power plants.

Biofunctional Characteristics of Lignite Fly Ash Modified ...

Fly ash superficially modified with humic substances from the Megalopolis lignitic power plant was prepared and evaluated for agricultural uses. UV-vis spectrophotometry and IR spectroscopy revealed that fly ash shows high sorption efficiency towards humic substances. Adsorption proceeds stepwise via strong Coulombic and hydrophophic forces of attraction between guest and host materials.
