SORPTION CHARACTERISTICS OF COOPER SORPTION ON THE CLINOPTILOLITE MEASURMENT

Abstract

Natural zeolite has found important uses in environmental protection and water treatment.In term of chemical, the zeolites belongs to hydrate aluminosilicates and against the their structure they have unique physical-chemical properties. This atribute affords the zeolites utilisation at water cleaning from metal ions. The most offen method of removing metals from solutions is precipitation, which is particularly effective at higher concentrations. In this way, but it is not always possible to reach limits that are set by law and therefore the use of zeolite is an appropriate way to final purification waste water after processing, for example. precipitation. Adsorption is among the most used and most economical method for removing cationic and anionic pollution. The possibility to use zeolites for this purpose, desirable attributes, such as high ion exchange capacity, good kinetics of ion exchange and sorption at low temperature, non-toxicity, resistance to aggressive media. Contents of this paper are the results of research on natural zeolite - clinoptilolite originating from the site in NižnýHrabovec, due to the sorption of coppercations.
