| description | Anion clay hydrotalcite MgAlCO3 with a Mg/Al molar ratio of 3:1 was synthesized
by co-precipitation at room temperature and pressure. The physicochemical
properties were evaluated using Powder X-Ray Diffraction (PXRD), Fourier
Transform Infrared (FTIR) spectroscopy and Thermogravimetric Analysis (TGA).
The efficacy of anion clay hydrotalcite in the removal of Cd2+ from aqueous solutions
was investigated with respect to contact time, initial concentration, pH, adsorbent
dosage and temperature. The Cd2+ removal increased with the increased in contact
time, adsorbent dosage, pH and initial concentration. Adsorption decreases with
increasing initial concentration and temperature, for which the latter is indicative
of an exothermic process. The equilibrium adsorption capacity of MgAlCO3 was
evaluated using linear Langmuir and Freundlich isotherms with respect to the separation factor, RL. |
