Marmara sea coasts has suffered from pollution for 30 years as a result of rapid and uncontrolled industrial development and intensive urbanization. There is an extensive water pollution problem, especially caused by the discharge of domestic and industrial wastewater loads, occurred in Marmara coasts.

In this study, we investigated removal conditions of some heavy metals from these wastewaters by a natural zeolite. The efficiency of the investigated clinoptilolite as an adsorbent, for removal of cadmium (II), copper (II) and nickel (II) ions from their aqueous solutions has been determined at different concentrations, zeolite amount, stirring speed and pH value. The adsorption experiments were carried out an laboratory batch mode at room temperature.

The results show strong support for the adsorption of some heavy metals on the clinoptilolite.
