Abstract
Experiments in natural porous media such as Eicchornia crassipes biomass for determining the sorption of arsenic are compared with numerical simulations done with the COMSOL Multiphysics code. The close agreement between the experimental and numerical results suggest that the theoretical model of hydrodynamic dispersion can be used to model the transport of arsenic in unsaturated porous media composed of Eichhornia crassipes biomass. The aim of this work was to find the best fitting between the experimental breakthrough curve and the simulated curve, during the arsenic sorption through the biomass.
