Abstract
In this study, zeolite Na-P1 synthesis from the fly ashes (FA) taken from dust catcher in Sugözü 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 MâH 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 1.5â¯T. Non-magnetic phase was accumulated in order to leach in alkali medium. 2â¯M NaOH was used as the synthesizing solution. Solid-liquid ratio was 0.3â¯kg:1â¯L. It was determined that the zeolitization degrees of the products depend on the reaction time. Zeolite Na-P1 (Na6Al6Si10O32·12H2O) which is the member of the group P zeolites was the dominant species after 10â¯h reaction time. Additionally, gismondine (Ca2Al4Si4O16·9H2O) 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/100â¯g to 388.85 meq/100â¯g.
