Abstract
Environmental pollution particularly at very low concentrations is very difficult to remove from contaminated media. Adsorption by means of relatively inexpensive natural adsorbents such as zeolites can be considered as a cost effective alternative treatment of such contaminated streams. The unique chemical and structural characteristics of natural zeolites made them potential materials for a multitude of environmental applications where materials are needed for effective binding, adsorbing, and filtering. In this chapter, some of the commercially available environmental treatment technologies based on utilization of natural zeolitic materials will be discussed.
Keywords: Natural zeolite, environmental pollution, wastewater treatment, ion exchange, adsorption, heavy metal, ammonium, radioactive waste.
