This diploma thesis is focused on the study of diffusion of metal ions in hydrogel of humic acid. The objective of this thesis was to investigate the effect of the concentration of metal ions supply source and duration of diffusion on transport through the gel using method of diffusion couple. Cupric, nickel and cobalt ions were esed like the diffusion medium. All these ions were selected thanks to their high affinity for the humic acids and because they are ideal to investigate the diffusion through the humic gel. Chloride salts of these metals, namely CuCl2, NiCl2 and CoCl2, were used like supply sources. Three different concentrations of each solution were compared, specifically 0,05M, 0,1M and 1M, and also were three different durations of diffusion, specifically 10 hours, 1 day and 3 days. Metal ions were compared with each other in order to determine which one has the best transport properties through the humic hydrogel. The data, necessary for calculation, were obtained by UV-VIS spectrophotometry. Diffusion coefficients and duffusive flux of individual metal ions were determined from measured data.
