Fly
ash generated during the combustion of coal for electricity generation in
coal-fired thermal power plants is a serious threat to the environment. The
problem of accumulation of fly ash in a sustainable way needs to be solved
urgently. There are many ways to resource fly ash, but high value-added
applications are rare. Many researchers have turned to carrying
out studies to eliminate heavy metal pollution by using natural and inexpensive
adsorbents. In this study, the chemical composition of the ashes belonging to
the Soma Thermal power plant and Scanning Electron Microscope (SEM) analysis
images were given. The optimum conditions under which the ashes will be
activated at different calcined temperatures (200oC, 400oC,
600oC, 800oC) and adsorb heavy metals have been
determined. In the optimization studies, the change of adsorption capacities of
fly ash depending on the adsorbed grain size, pH and temperature was studied. The
adsorption capacity and the amount of adsorbed substance were determined using
polarographic methods. The high adsorption capacity of fly ash, which is a
solid waste problem around the Soma thermal power plant, has increased its
importance in terms of using ash in the treatment process.
