Natural zeolite-clinoptilolite (from Vranjska Banja deposit in Serbia) and synthetic Beta zeolite,
were amin-functionalized using (3-aminopropyl)-triethoxysilane (APTES). 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. Natural zeolite-clinoptilolite
showed a higher adsorption capacity (96 mg Ag/g), compared to beta zeolite (54 mg Ag/g) which is
attributed to the presence of exchangeable cations in the structure of clinoptilolite. 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 zeolite. Ag-APTES and APTES-enriched zeolites
further were studied as antibacterial agents toward the pathogenic bacteria Gram-negative
Escherichia coli DSM 498 a...nd Gram-positive Staphylococcus aureus ATCC 25923. Based on the
results, it was concluded that the APTES-zeolites do not exhibit antibacterial activity while Ag-
APTES enriched zeolites shows antibacterial effect toward both examined bacterial strains.
Antibacterial activity is attributed to the presence of silver ions.
