Trends and Perspectives Regarding the use of Natural and Synthetic Zeolite Systems in Environment Protection (Review)

The zeolite material that is available nowadays for the confection of devices and systems that are used in environment protection is represented by an ensemble of natural modified zeolites and synthetic ones that ensure the adsorption of various pollutants. Natural zeolites facilitate ion exchanges, absorption and catalysis, these proprieties securing their use as protectors and restorative for polluted water, soil and plants. The modification of zeolites is represented by a transformation of the natural zeolite into cheaper adsorbent materials that are very efficient in the purification of environments that have been polluted with heavy metals. This review summarises the application of natural and modified zeolites in the protection and decontamination of the environment
