A hydrotalcite was subjected to mechanochemical treatment using a vibration mill. The treated samples were characterized using x-ray diffraction (XRD) measurement and thermal analysis. Unlike other clay minerals, the crystal of mechanochemical treated hydrotalcite was reduced parallel to the layer and perpendicular to the layer. The thermal analysis revealed the increasing of surface adsorbed water on the treated samples, which shows the surface areas of the samples were increased. The treated samples show drastic improvement of fluoride adsorption capacity.
