The magnetic zeolite LTA was successfully synthesized using NaOH activated fly ash. The properties of the magnetic zeolite LTA were characterized by XRD, FTIR, SEM, TEM, BET, and VSM. We can be concluded that the synthesized composite consists of zeolite LTA and magnetic Fe(3)O(4)nanoparticle. The nitrogen adsorption technique confirmed that the magnetic zeolite LTA exhibits a specifific surface area of 10.0183 m(2)center dot g(-1), which is much larger than that of the fly ash. VSM result confirms that the magnetization saturation value of the magnetic zeolite LTA is 10.06 emu center dot g(-1). Therefore, the magnetic zeolite LTA could be easily separated from the liquid phase using a magnet.
