Abstract:
The phenomena of copper, hexavalent chromium and zinc adsorption by activated carbon samples prepared from different native woods was studied to select an appropriate sample for maximum adsorption in each of the case. The activated carbon prepared from Eucalyptus (E. camaldulensis), a hardwood, has overall shown better adsorbing behaviour. The pH of the metal solution has been found to be the principal variable affecting the adsorption. It was thereafter concluded that in the case of copper and zinc, there was no significant adsorption below pH 4 and in case of Cr +6 optimum pH is 2 for maximum adsorption, gradually decreasing with increasing pH of the metal solution.
