Transport of reactive colloids and contaminants in groundwater: effect of nonlinear kinetic interactions

摘要

Transport of reactive colloids in groundwater may enhance the transport of contaminants in groundwater. Often, the interpretation of results of transport experiment is not a simple task as both reactions of colloids with the solid matrix and reactions of contaminants with the solid matrix and mobile and immobile colloids may be time dependent and nonlinear. Further colloid transport properties may differ from solute transport properties. In this paper, a one-dimensional model for coupled colloid and contaminant transport in a porous medium(COLTRAP)is presented together with simulation results.
