An adsorbent composition comprising a nanoscale metal hydroxide or oxide coating is provided in an organic tempered bohemite nanoarchitecture (OTBN). The nanoscale coating is prepared by impregnating OTBN with a metallic or non-metallic ion, followed by in situ hydrolysis of the ion deposited on the surface of the OBTN. The thickness of the coating is less than 3 nm, which is less than the core size of the OBTN. The amount of layers of the coating is flexible, thus giving rise to a nanoscale hybrid composition of multiple layers. The adsorbent composition can remove inorganic anions, such as fluoride, from the water with a greater adsorption capacity. |
