Natural zeolites are highly effective adsorbents that can remove various metal cations which would otherwise contaminate the environment. However, different (Cu, Zn, and Ag) within their lattice or quaternary long-chain surfactant on surface modify affinity towards hazardous anions promote antibacterial activity in natural zeolites. Specifically, non-modified form lack intrinsic characteristics. NZ is most widespread zeolite. This review presents efficiency of containing transition metals, nano oxides, organics. effect nonspecific primarily driven by nutritional makeup medium rather than species pathogenic bacteria under study. Studies using NZ-based disinfectants to clean up contaminated water soil modified purified protect health also considered. By eliminating toxic ions and, when these cations, removing pathogens from environment, serve a dual function, providing it with distinctive characteristics sustainable material.
