The sorption capacity of the native Romanian clinoptilolite and analcime employed for removing Cu2+ ions from wastewater was investigated under various conditions of temperature, time and solution concentration. These parameters are necessary and sufficient for developing a mathematical model of the sorption process. The corresponding mathematical models show common characteristics due to the good arrangement of the experimental points on the response surfaces and correlation coefficients close to unity. Differences appear with respect to the shape of the response surface and model equations.
