Abstract
In this research two types of activated carbon (AC) were prepared from Sudanese
Nabag shells. The first one of AC was prepared by pregnating the shells with
sulphuric acid before carbonization. The second type of AC was prepared without
chemical treatment.
The percentage yield of the products were calculated and found to be 32.31% for the
AC treated with acid and 24.88 % for AC prepared without chemical treatment. The
functional groups for the two carbons were determined by FT-IR technique and the
results showed the presence of O-H, C-H and Si-O in the two types of AC.
The equilibrium time for the adsorption of cadmium ions at room temperature was
determined and was found to be 20 minutes for the carbon prepared with acid and 10
minutes for the one prepared without chemical treatment. The adsorption efficiency
and sorption capacity for these carbons was studied at different adsorbate
concentrations. It was found that, the carbon prepared without acid showed a higher
adsorptive capacity for removal of cadmium ions compared to the AC prepared with
acid. They showed removal percentages of 50.2% and 14.77% at the same concentration and time respectively.
