"The aim of this work is the study of interactions between humic acids and copper (II) ions in diffusion experiments. The diffusion experiments were combined with selective extraction of diffused copper (II) ions. The results showed that diffused ions are in humic gel presented in more forms according to the bond strength towards humic acids. Their distributions into the individual fractions developed in time and were stabilized."@en .
