Layered Double Hydroxides as Active Environmental Cleaners of Polluted

Environmental problems are more prevalent nowadays and one of the big concerns is water contamination by highly toxic pollutants. The employment of adsorption technologies constitutes a powerful tool for the reduction of water pollution because of the mild conditions required by adsorption and its good efficiency in pollutant removal processes. Defined by a versatile micro/nanotexture layered double hydroxides (LDH) can be fabricated to own specific nanoarchitectonics hence, they are proposed nowadays as efficient adsorbents. This work presents MgAlLDH and the derived calcined forms to be employed as efficient adsorbents to treat aqueous mediums polluted with industrial dyes (e.g.: Nylosan Navy). Results reveal a strong connection between the adsorption efficiency and the micro/nanomorphology features of the LDH. The structure and morphology properties of the LDHs were studied by XRD, FESEM and N2 adsorption techniques. These findings might pave the way to establish novel solutions to remove toxic compounds from aqueous mediums by using LDHs as efficient environmental cleaners in water technologies
