Synthesis of Ni-Al layered double hydroxide nanoparticles and the investigation of theabsorption of acid Brown ۱۲۱ dye by them

The Ni-Al-layered double hydroxide (LDH) nanoparticles were prepared with Ni/Al molar ratioof ۳:۱ by a thermal process and co-precipitation method at pH ۶ in a mixture of deionized water and glyceroland were characterized by X-ray powder diffraction (XRPD), thermal gravimetric analysis (TGA) and atomicadsorption spectroscopy (AAS). The size and morphology of nanoparticles were examined by transmissionelectron microscopy (TEM). Ni-Al-LDH was studied as a potential adsorbent of the acid Brown ۱۲۱ dye asfunction of pH, contact time and temperature. The results showed high and fast adsorption on the LDH.
