Abstract:
The study was undertaken to prepare and characterize the adsorbent using eggshell and
determination of removal efficiency of Cr6 and Total Organic Carbon (TOC). Unheated adsorbent and
heated (at 1500C) adsorbent were prepared. Characterization of adsorbent was performed by
Scanning Electron Microscope (SEM). Elemental Analysis (EA) and Fourier transform infrared
spectroscopy (FTIR). The Eggshell surface showed porous nature. This study showed that heated
eggshells adsorbed more rapidly and efficiently than unheated adsorbents. Heated eggshell removed
twice the amount of Cr6 than the Cr6 removed by unheated eggshell. When both heated and unheated
eggshells were used to remove TOC, the load of TOC increased. This may be caused by the release of
organic carbon from the adsorbent.
