Original Abstract
The mobility of Cu(II) ions in humic gels with respect to their reactivity and concentration dependence is investigated in this work. Two various methods: instantaneous planar source and constant source were used in order to study their diffusion at very low and very high Cu(II) concentrations, respectively. It was confirmed, that the higher concentration gradient in method of constant source supports mobility of Cu(II) ions, which corresponds with higher values of computed diffusion coefficients. The diffusion coefficient was more influenced by concentration change in case of gel prepared from Na5P3O10 as a result of less stable complexes formed in the gel with Cu(II) ions.
