This contribution summarizes the rich collection of experiments which have recently focus on utilization of simple transient and steady-state diffusion experiments in revealing the effect of interactions of charged organic compounds (low-molecular cationic dyes) with humic acids fixed in a suitable hydrogel matrix (agarose gel). The hydrogel support is used in order to simulate the state of humics in their natural environments and also to allow preparation of a sample in properly described form (in sense of its size and shape) which is necessary for correct data evaluation. Diffusion-cell and in-diffusion experiments have been performed in order to determine the effective diffusion coefficients of the model charged organic compounds in hydrogels with different content of humic substances. Results were interpreted using the comprehensive theoretical model, derived for the diffusion of solutes in the porous media, in order to calculate some structural (tortuosity) and interaction (binding constants) parameters of the studied systems.
