SINOPSIS

The diffusion of solutes in the environment tends to deviate from Fickian assumptions at higher solute concentrations. In order to understand the degree of deviation in the diffusive transport of species, diffusion experiments through porous media using sodium chloride is conducted. The results obtained from the experiments showed a linear relationship between chloride diffusivity and square root value of chloride concentration. The relevance of diffusion coefficient function in the transport studies is also established using numerical simulation studies involving diffusion coefficient function and diffusion coefficient at infinite dilution.
