The effect of preparation conditions on the ion-exchange properties of LTA zeolite prepared from
local silica
Samia A Kosa
King Abdulaziz University, Saudi Arabia
In this study LTA, zeolite was prepared from Saudi white silica as a main source of silica. The effect of ultrasonic irradiation
on the crystal structure and ability to ion exchange of some heavy metals were studied. Many techniques were used to
characterize the prepared zeolite includes XRD with crystal lattice analysis, EPR and finally ion exchange isotherm of some
heavy metal ions. The results showed that the ultra-sonicated zeolite exhibits different behavior towards ion exchange with
increasing its capacity. The ultra-sonicated zeolite showed little increase in the lattice parameters with increasing in the crystal
size. Fitting adsorption isotherms on the metal adsorbed showed an observable change in the behavior of ultra-sonicated
zeolite towards the metals exchanged.
