Copper(II) was selected as a model ion and Cu2+ exchange batch and column studies were made using natural zeolite samples having different clinoptilolite contents. 8.33 and 10.00 mg/g copper ion exchange capacities were determined for zeolites with 64% (CP2) and 80% (CPI) clinoptilolite contents, respectively. It has quantitatively been shown that Cu+2 ions were exchanged with Na+, K+, Ca2+ and Mg2+ ions. Flow rate had the most important effect on breakthrough point rather than column height and inlet solution concentration for column studies.
