Sažetak
A class F fly ash from the Croatian power plant Plomin 2 has been used for the sorptive removal of cobalt ions from aqueous solutions by a batch technique. The experiments were carried out as a function of solute concentration at constant temperature (298 K) and particle size (< 45 μm). Langmuir, Freundlich, Dubinin-Radushkevich, Redlich-Peterson, Sips and Toth isotherms were fitted to experimental data, and their goodness-of-fit were compared. According to the results obtained, the sorptive removal of cobalt ions is process of homogeneous adsorption as the Redlich-Peterson and Langmuir isotherms were found to give a better fit to experimental data than other isotherms that take into account some sort of heterogeneity. The results indicated that fly ash class F can be used for the removal of cobalt ions from wastewaters.
