INVESTIGATION OF ION EXCHANGE AND MAGNETIC PROPERTIES OF MAGNETICALLY MODIFIED ZEOLITE 13X

Abstract

The papers on magnetic modification processes were firstly published about synthetic zeolites and studies still continue Petridis et al [1], Čapek et al [2]. The literature review, which we have done up to now, shows that there is no study about magnetic modification process for 13X zeolite or that we haven’t found one even if there were one. For this reason, this study was realized on magnetic modified 13X zeolite about magnetically modification by using magnetite obtained from Divriği region, Turkey. After modification process, samples were characterized by XRD, XRF, SEM, EDX, VSM. Then, ion exchange and magnetic properties of unmodified and modified zeolites were compared with each other. According to these findings, modified zeolites have better ion exchange and magnetic properties than the others.
