  ABSTRACT: Zeolitic material as Na-mordenit (SiO2/Al2O3 = 10) was synthesized on the basis of natural raw material volcanic ash, in presence of organic components tetraetilamonium iodide (TEAI). The ash sample used in the laboratory experiments contains 67%, 56% SiO2 and 12.48% Al2O3, abundances. The reaction time as well as the influence of TEAI was studied in the zeolitic materials crystallization. The experiments were carried out under hydrothermal conditions, autogenic pressure and temperature of 220℃, as well as reaction time from 48 to 240 h. Products from this hydrothermal treatment were identified by the rentgenophase analysis methods on the apparatus of BRUKER D2 PHASER and weight-spectroscopic analysis method on the apparatus of ICP-MS Agilent 7700. Of the zeolitic material, the Na-mordenit zeolite was found to be the most effective for the retention of cations Pb2+, Zn2+ and Ba2+.
