摘要：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.
