“…Various materials incorporated with silver zeolites have been investigated, including zeolite/ polymer composites, synthetic polymers, biopolymers, zeolite/textile composites, zeolite/metal coatings, dental materials, environmental/consumer materials (Dutta and Wang, 2019). Nanoporous zeolite modified by silver ions that could be applied in anticorrosive protective material, was deemed effective against P. aeruginosa bacteria (blue pus bacillus) (Znak et al, 2021). Gelatin-based films containing silver clinoptilolite with a glycerol concentration of 25% and zeolite concentration of 0.5% resulted in films with more suitable properties for wound dressing applications.…”

The present review summarizes research on the antimicrobial properties of modified natural zeo¬lite clinoptilolite. The modification of the clinoptilolites is based on its ion exchange features with silver, copper, zinc, or other ions in order to obtain antimicrobial properties. The review includes recent data on pretreatment and preconditioning to increase the effectiveness of ion exchange procedures and obtain a functionalized zeolite. The review covers antibacterial, antifungal, and antiviral activity materials based on natural zeolite clinoptilolite.

“…[17][18][19] The high antibacterial capacity of synthesized silver nanoparticles and composites based on them has already been confirmed. 17,[19][20][21] Silver as an antibacterial agent in clinoptilolite can be in two forms. The first one is in the form of solid-phase highly dispersed or nano-sized particles, mostly deposited on the zeolite surface.…”

Areas of use of natural clinoptilolite were analyzed. The emphasis was placed on its application in water technology and medical practice. The results of the study of the dehydration of clinoptilolite at different temperatures were presented. The influence of the activation temperature of clinoptilolite on its sorption capacity for silver ions was determined. The effect of modification with ions and highly dispersed silver particles on the sorption capacity of various zeolite fractions with respect to water was investigated.

“…One of the most important properties of zeolites is their sorption capacity for various compounds, which is determined by the effective diameter of the entrances to the cavities. Clinoptilolite, a heylandite zeolite, is widely used [3][4][5][6] in a variety of fields. It belongs to one of the most stable and widespread types of natural zeolites in the world, deposits of which are available in Transcarpathia region.…”

The widespread application of Ukrainian natural zeolites in sorption and catalysis is limited by the shortcomings of their porous structure. Chemical modification of zeolites permits significant changes in their properties. The purpose of this work was to obtain silver-containing natural zeolites of the clinoptilolite type with improved porous characteristics by acid treatment and to study their antibacterial properties. Mild dealumination of the rock was carried out using ethylenediaminetetraacetic acid for 15 hours at 90 °C, which significantly increased the specific surface area of the clinoptilolite sample to 90 m2/g, and the volume of micropores to 0.037 cm3/g, determined by low-temperature nitrogen adsorption/desorption. An establishment of a change in the chemical composition of the sample during processing by X-ray fluorescence analysis was made. Additional modification with silver in the amount of 1 wt % was carried out by impregnation with a solution of silver nitrate. The water of three lakes in Kyiv was studied for the total viable count by means of sowing in nutrient agar. The results were analyzed and a sample of water was selected to evaluate the effectiveness of the synthesized sorbent. The antibacterial properties of zeolite were confirmed with the worst of the water samples, the quality of which, in terms of the total viable count, was improved not only to the norms of surface water but also to the indicators for drinking water.
