Material was characterized using FTIR and XRD analyses and used as adsorbent of procion red dye in aqueous medium. &nbsp;Factors that affect the adsorption process are adsorption time as the kinetic parameter; and the temperature and concentration of procion red as the thermodynamic parameter. FTIR spectra of layer double hydroxides showed unique vibration at wavenumber 1300 cm<sup>-1</sup> and 1600 cm<sup>-1</sup>. Characterization using XRD shows diffraction angles at 29<sup>o</sup>, 27<sup>o</sup>, and 28<sup>o</sup>, which are typical of Mg/Al double layer hydroxides. Adsorption of procion red using layer double hydroxide Mg/Al resulted adsorption rate 7.1 minutes<sup>-1</sup>, maximum adsorption capacity 111.1 mg/g at 60 <sup>o</sup>C with increasing energy by increasing adsorption temperature. &nbsp;</p><p><strong>Keywords:</strong> Layered double hydroxides, adsorption, procion red.</p> ER -
