| Abstract: | The dynamic adsorption of Pb(II)
ions from aqueous solutions using a granulated activated carbon and an
activated carbon cloth has been studied using fixed bed adsorption column. The
breakthrough curves at different hydraulic loading rates (HLR), bed depth and
feed concentration (Co)
have been examined. The breakthrough
time at any given concentration of the effluent decreases with increasing
hydraulic loading rate and feed concentration but increases with increasing bed
depth. The adsorption capacity of the carbon bed increases with increasing HLR
and attains a maximum value at HLR of 1.22 m3/h/m2. The
adsorption zone parameters and column design parameters have been determined
using BDST, Yoon-Nelson and Wolborska models. The experimental values obtained
from column experiments agree fairly with the theoretical values obtained using
different equations. The design parameters obtained from one column experiment
have been used to design adsorption column for any other flow rate and feed
concentration. |
