ANALIZA REGRESJI IZOTERM SORPCJI JONÓW MIEDZI I KADMU NA IŁACH SMEKTYTOWYCH

Abstract

REGRESSION ANALYSIS FOR THE SORPTION ISOTHERMS OF COPPER AND CADMIUM IONS ON SMECTITE CLAYSAbstract. The sorption of Cd(II) and Cu(II) ions onto smectite clays was studied. Equilibrium isotherms were analyzed using the Langmuir and Freundlich isotherms. A comparison between a linear and non-linear method of estimating the isotherm parameters was made. The results show that the non-linear and linear methods in two ranges of initial metal concentrations could be the best way to obtain the parameters.
