Removal of cadmium ions from aqueous solution by using regular MgAICO3 hydrotalcite / Zawati Endut
Hydrotalcite (MgAlCO3) was found to have ability to exchange anionic species and absorb the cationic species that obtain to remove heavy metal from aqueous system. In this study, Mg/AlCO3 was synthesized by co-precipitation method. Characterization of hydrotalcite by using X-Ray Diffractogram (XRD)...
