Abstract
Activated carbon (AC) which produced from peanut shells by either chemical activation with different reagents such as (NaOH, ZnCl2 and H2SO4) or by physical activation with steam were used for the minimization of methomyl, methylene blue and lead(II) and were characterized by SEM, FTIR, Boehm titration, point of zero charge and nitrogen adsorption–desorption analysis. The parameters (such as initial pH, temperature... etc) affecting the adsorption capacity of ACs toward the minimization of methomyl, methylene blue and lead cation minimization from aqueous solutions are investigated using batch experiments. The isotherm data were analyzed using the Langmuir and FreundlichEqs. The kinetic results were analyzed using pseudo-first order, pseudo-second order, intraparticle diffusion and the Boyd Eqs. The thermodynamic parameters including ΔG°, ΔH° and ΔS° for the adsorption processes of pollutants on the carbons were calculated. The desorption studies of some samples from ACs were performed. The potential application of the activated carbon samples for minimization of heavy metals (Pb (II) as model), methomyl and methylene blue from different types of water was evaluated.
