Abstract

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.
