Abstract

Adsorption of metal ions Cu(II), Zn(II) and Cr(VI) on SDDC (sodium diethyl dithiocarbamate)- modified activated carbon in an adsorption column were kinetically modeled in this article. Two types of activated carbons, regular and modified, were considered. For this purpose, the experimental data of Monser and his co-worker for adsorption of metal ions on those two types of activated carbons were adopted. The kinetic modeling of these systems shows that the intra-particle diffusion of the ions is the controlling mechanism for their adsorption on activated carbon. The effective diffusion coefficients of all three ions in the regular activated carbon were calculated as 2.25 x 10-12 m2/s. The effective diffusion coefficients of those three ions in SDDC-modified activated carbon were found to be 50% higher than those in the regular activated carbon.
