Zeolites are inorganic, crystalline aluminosilicates that nowadays has been used as
adsorbents, catalysts and carriers of catalytically activated substances, due to the small size
of their pores, large internal surface, and well-defined chemical composition. In this paper,
the modification of beta zeolite using (3-aminopropyl)-triethoxysilane (APTES) was
investigated. The results of the Fourier transform infrared spectroscopy and
thermogravimetric analysis confirmed the presence of amino groups derived from APTES
onto the modified zeolite surface. APTES-enriched zeolite was further used as an adsorbent
of silver ions from aqueous solutions. The obtained results reveal that a zeolite after
modification exhibited significantly better adsorption efficiency (97%) in comparison to the
unmodified (37%). The kinetic data follows the pseudo-second-order model which
indicates a chemical interaction between silver ions and functional amino groups on the
surface of the silanizedbeta ze...olite. Ag-APTES enriched beta zeolite also was studied as
anantibacterial agent toward the pathogenic bacteria Gram-negative Escherichia coliDSM
498 and Gram-positive Staphylococcus aureus ATCC 25923.
