Sorption of Congo Red anionic dye on natural hydrotalcite and stichtite: kinetics and equilibrium

The sorption properties of two layered minerals of the hydrotalcite supergroup – hydrotalcite and stichtite – were investigated with the aim of determining their kinetic parameters of sorption and their adsorption isotherm type. Pristine hydrotalcite and stichtite were characterized using X-ray diff...
