In this study, zeolite Na-P1 synthesis from the fly ashes (FA) taken from dust catcher in Sugozu thermic power plant was researched. The structural and magnetic characteristics of the synthesized materials were studied by using the XRD, SEM, EDS, CEC, TGA, DTA, DSC and M-H techniques. High intensity wet magnetic separation was applied to the ashes at different magnetic field intensities. 61% of the iron oxide impurity (Fe2O3) was removed by single-stage high intensity wet magnetic separation at 1.5 T. Nonmagnetic phase was accumulated in order to leach in alkali medium. 2 M NaOH was used as the synthesizing solution. Solid-liquid ratio was 0.3 kg:1 L It was determined that the zeolitization degrees of the products depend on the reaction time. Zeolite Na-P1 (Na6Al6Si10O32 center dot 12H(2)O) which is the member of the group P zeolites was the dominant species after 10 h reaction time. Additionally, gismondine (Ca2Al4Si4O16 center dot 9H(2)O) presence was observed in the products. It was found out that the ferromagnetisms of the products were weakened by elapsed time. The CEC values of the synthesized products were the superior grades ranging from 269.63 meq/100 g to 388.85 meq/100 g. (C) 2018 Elsevier B.V. All rights reserved.
