SINOPSIS

Diffusion is one of the most widespread transport processes in nature, and quantifying the diffusion process has considerable practical significance in all fields of science and technology. The transient behavior of the diffusion coefficient observed in real systems raises doubts regarding the validity of the linear Fickian equation. A better characterization of transport can be attempted by incorporating concentration-dependent diffusivity into the diffusion transport equations. Such investigations require availability of functional relationships between the solute concentrations and corresponding diffusion coefficient. Results of diffusion experiments using four binary electrolytes − NaCl, KCl, MgCl2, and CaCl2 in two nonreactive porous systems − glass beads, and pure fine sand is presented in this article. Even processes such as adsorption, precipitation, dissolution, and other chemical reactions cannot be explained well without detailed knowledge of diffusive transport. The results obtained in this study would help us to adopt better predication techniques for solute transport in porous media and hence provide useful insights for developing more efficient design approaches.
