Abstract

The presence of heavy metals in ecosystems has many negative effects on human health and the environment These ions do not undergo microbial or chemical degradation and their total concentrations in soils tend to persist and thus may cause severe problems for living organisms [I]. Therefore, due to these disadvantages, various techniques such as adsorption, extraction, plant extraction, ultrafiltration, reverse osmosis, electro dialysis, ion exchange and membrane processes for the removal of heavy metals have been proposed [2]. Zeolites are microporous crystalline hydrated alumina-silicates characterized by a three-dimensional network of tetrahedral (Si, Al)04 units that form a system of interconnected pores [3]. In this study, HY zeolites are functionalized by organic compounds containing nitrogen atoms and their role in the removal of heavy metals is investigated. The synthesized HY zeolites are detected by powder X-ray diffraction, scanning electron microscopy, nitrogen adsorption isotherms and FTlR spectroscopy [4J. The synthesized HY zeolites structure are is characterized by powder X-ray diffraction, scanning electron microscopy, nitrogen adsorption isotherms and FTIR spectroscopy [5].
