Evaluation and Comparison of Antimicrobial Properties of Natural and Synthetic Zeolites Exchanged with Silver, Zinc, Copper and Nickel Ions

Zeolites are high-porous active crystalline biomaterials. Recently many studies have been done on their antibacterial properties especially zeolites exchanged with metallic cations. In this paper, we investigate the effective factors antimicrobial activity of natural and synthetic silver, zinc, copper nickel, bromide This study reviews published articles pure as well ion exchange ones. The results our investigation show that exhibit a very good effects even in comparison other conventional materials. strongest was reported silver against Bacillus cereus Escherichia coli MIC 16 μg/ml. According to derived from different articles, it can be concluded biocompatibility high capacity used efficient Pure at concentrations, whereas all metal cations investigated paper low concentrations generally due sustained prolong release
