Abstract
Complex formation reactions with the interaction of fulvic and humic acids with zinc and iron ions in a model aqueous system. The complexing ability of humic acids was experimentally proved to be much higher than that of fulvic acids. The complexing ability of fulvic acids is found to decrease over time. The dependence of the complexing ability of heavy metals on the types of ion and humic substances and the proportions of components in the solution is examined. The obtained experimental results on the occurrence forms of heavy metals were compared with their theoretical estimates calculated for natural water bodies.
