Physicochemical characterization for different types of soil used in Heavy metals removal from aqueous solution
description Heavy metals are one of the main contributors to water pollution worldwide. The adsorption study using soil known to be a promising technique to remove heavy metals from aqueous solution. The previous study claimed that these three types of soil (red-earth, clay and sandy soil) have successfully adsorbed considerable quantities of heavy metals such as lead (Pb) and cadmium (Cd) ions from aqueous solution. Thus, this study intended to examine the physicochemical characteristics of three types of soils (red-earth, clay and sandy) which acted as adsorbents material to remove the heavy metals from aqueous solution. All soil sample types were characterized and analyzed using Field Emission Scanning Electron Microscope- Energy Dispersion X-ray (FESEM-EDX), Fourier Transform Infra-Red (FTIR) and Brunauer, Emmett and Teller (BET).
