چکیده مقاله:

Widespread abundant resources of natural zeolites are in Indonesia. Sedimentary zeolite deposits have been discovered at Java, Sumatra, Sulawesi, Flores and Lombok Islands. In an attempt to utilize natural zeolites as anti bacterial material, some of natural zeolites have been characterized and modified by treating with aqueous HCl solution and EDTA followed by impregnation of a small amount of TiO2 and cation Ag+. The nano particles of TiO2-Ag+ was characterized by using XRF, FT-IR, X-ray Diffraction and DRUV. Antibacterial activities was tested for Escherchia Coli and Salmonella Typhi bacterias, while for jamur it was used Candina Albicans fungi. The activities of the resulted antibacterial zeolites was compared to the Iraguard 600 activities. The experimental results indicated that nano particles of TiO2-Ag+ was successful obtained in the particle size approximately of 10 nm. The antibacterial activities of the resulted antibacterial zeolite shown better activities compare to the Iraguard 600.
