Adsorption of zinc and copper ions on natural and ethylenediamine modified montmorillonite

Original language description

In this study, adsorption of the zinc and copper ions on montmorillonite (MMT) was investigated. In all experiments performed at pH 6.4 to 4.8, the Langmuir-Freundlich isotherm was found to best fit adsorption data that confirms a monolayer formation ofthe metals. The maximum amounts of the adsorbed metals did not exceed a cation exchange capacity (CEC) of MMT. UV-VIS diffuse reflectance spectrometry reveals no complexes between Zn2+ or Cu2+ and MMT and thus the metal uptake took part only by ion exchange. X-ray diffraction (XRD) patterns indicated an intercalation of the metal ions into the montmorillonite interlayer. In addition, using thermogravimetry and infrared spectrometry it was found the intercalated metals create aqua complexes [Zn(H2O)6]2+and [Cu(H2O)6]2+. In order to increase the adsorbed amounts of Zn2+ and Cu2+, MMT was previously intercalated with ethylenediamine (EDA-MMT).
