Abstract:
The capitalisation of ash from power plant for obtaining zeolites is very interesting, because obtained products have
high environmental applications. Zeolites may be easily obtained from ash by direct alkaline conversion processes,
diffusion process and microwave. The zeolites have been researched for a variety of environmental applications in
agricultural, they have remarkable properties: cation-exchange, adsorption, and molecular sieving properties.
From the types of zeolites which may be obtained, in this study are presented different zeolitic products for wastewater
with high CEC. The zeolitic products which were obtained were analyzed as composition and properties. The
synthesized products provide a significant increase of CEC and a high ability to adsorb heavy metal ions.
The aim of this study is establish the experimental conditions f or power plant ash zeolitization. On the base of their
cation-exchange properties, zeolites can be use for cation-exchange in wastewater.
