Proposed adsorption-diffusion model for characterizing chromium(VI) removal using dried water hyacinth roots
Volume: 38
Issue: 8
Pages: 764 - 770

Experiments have been carried out to characterize the adsorption of chromium(VI) in the aqueous phase onto dried roots of water hyacinth. Results revealed a very high degree of removal efficiency (~100%). Theoretical analyzes are also made for describing the sorption and diffusion processes. The effective pore diffusivity of chromium(VI) in the water hyacinth roots is determined by a suitable global optimization technique. The depth of penetration, on the other hand, has been estimated for various initial concentrations of chromium(VI). Theoretically predicted concentration profiles are in excellent agreement with the experimental values. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
