Ni-Mg-Al-LDH was prepared by the co-precipitation method then calcined at 790C for 6h-12h, which transformed it into Ni/Mg/Al oxides. Samples were irradiated for 15min-30min-1h-2h to enlarge the host layer. Both calcined and irradiated Ni-Mg-Al-LDHs were examined for iodide capture. Adsorption experiments were carried out at different iodide concentrations, i.e. 24-45ppm. The12h calcined LDH showed the highest iodide uptake. All samples were characterized by X-ray spectroscopy, and infrared spectroscopy.
