Sažetak
In the last few decades the importance of environmental protection, among other things, resulted in the intensive study of zeolites as ion-exchangers. Use of this technique has dual application: for the removal of heavy metals from wastewaters and for the preparation of catalysts. For this reasons the equilibrium of sorption of copper ions from aqueous solutions using synthetic zeolite X has been studied by a batch technique. The experimental data obtained at constant temperature for the different initial concentrations of copper solutions have been analyzed using six types of isotherm models Two two-parameter isotherms, two three-parameter isotherms and two four-parameter isotherms. Non-linear regression method was used in order to calculate parameters of the isotherms. According to chi-square value the most appropriate equation for describing experimental equilibrium data was Radke-Prausnitz isotherm. This isotherm was combined with reactor model for batch reactor design.
