Popis:	In the present study, the influence of coal fly ash's particle size on uranium (U) decontamination from water samples is investigated. Accordingly, fly ash is segregated into five different size fractions (i.e., 63–90 μm, 125 μm) using an electromagnetic sieve shaker. Adsorption experiments are carried out in triplicate samples (for equilibration time at pH 6) using a laboratory batch method on all the size fractions with known U concentration. The highest U adsorption is observed for the lowest size fraction (i.e.
