Abstract:
Five hydrotalcite-like compounds with different Mg/Zn ratio were prepared and characterized from a structural
point of view, in order to be used for chromate uptake from wastewater. The chemical composition of the materials was
determined using EPMA (electron probe microanalysis). The thermal behavior was investigated by DTG method. The
structure of as-synthesized hydrotalcite-like samples was confirmed by X-Ray Diffraction and FTIR Spectroscopy
methods. A part of the samples were activated in an oven, at temperatures of 500°C in air, with a rate of 5°C/min for 4
hours and the specific surface area of calcined compounds was measured.
