Abstract
In this study LTA zeolite was prepared from kaolin. 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 X-ray diffraction analysis (XRD) with crystal lattice analysis,
Electron paramagnetic resonance (EPR) and finally ion exchange isotherm of
some heavy metal ions. The results showed that the ultrasonicated zeolite ex-
hibits different behavior towards ion exchange with increasing its capacity.
The ultrasonicated zeolite showed little increase in the lattice parameters with
increasing in the crystal size. Fitting adsorption isotherms on the metal ad-
sorbed showed an observable change in the behavior of ultrasonicated zeolite
towards the metals exchanged.

1. Introduction
The preparation of zeolites from clays and raw materials was a subject of many
researches in the past decades [1] [2] [3] [4]. The zeolites were considered to be
three dimensional alumino silicate structures consists of tetrahedral of TO
4
(T, Si
or Al). The resulting combination of these tetrahedra resulted in excess negative
charge which balanced by a mobile cation [5]. These distinct proprieties of zeo-
lite enable it form perfect performance in ion exchange. In addition to that, the
three dimensional arrangements inside the zeolite structure add a variety of
porous structures within the range of micropores [6] [7]. Many synthetic zeolites
require what is called template, acts as a directing agent to the required pores [8]
