The nanostructural materials Zn/Al layer double hydroxide (Zn-Al /LDH) were prepared via a one-pot co-precipitation method, with different (Zn²⁺ /Al³⁺) molar ratios (2, 3 and 4). The synthesized samples were characterized by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Nitrogen Physisorption (BET) and Scanning Electron Microscopy coupled with Energy Dispersive X-ray Spectroscopy (SEM/EDX). The XRD spectra obtained for the synthesized samples exhibits a series of characteristic reflections of well-crystallized hydrotalcite-like structure and the Brunauer-Emmer-Teller analysis (BET)   confirm that the samples exhibit a strong characteristic of mesoporous materials.

The synthesized materials were assayed in the adsorption of organic polluant in aqueous solution. Experimental results indicated that the adsorption of polluant onto Zn(2)Al-LDH followed the Freundlich isotherm model. The Zn^2+/Al³⁺ molar ratio was found to affect the adsorption process. The facile, low-cost preparation and efficient removal of pollutants makes the LDH materials advantageous.
