Assessment of the efficiency of animal bones and neem leaves adsorbents in the removal of Cadmium ions from aqueous medium
The sorption efficiency of bones and neem leaves adsorbents for the removal of cadmium ions from wastewater was investigated in the study. The animal bones and neem leaves were carbonized and activated using phosphoric acid. The adsorbents were characterized by scanning electron microscopy, Fourier...

| description | The sorption efficiency of bones and neem leaves adsorbents for the removal of cadmium ions from wastewater was investigated in the study. The animal bones and neem leaves were carbonized and activated using phosphoric acid. The adsorbents were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, x-ray diffractometry and atomic absorption spectrometry. The equilibrium sorption properties were assessed to optimize the conditions for maximum sorption of the cadmium ions. As for the samples of neem leaves, it was observed that the activated carbon prepared from neem leaves had a high adsorption efficiency of 73.13% than that of raw neem leaves of 67.53% and activated leaves having the lowest efficiency of 25.49%. From the values obtained for animal bones, the carbonized sample had the highest efficiency of 75.22% and the raw sample had high efficiency of 74.23%. |
