| Popis: | Interaction of humiс substances with iron ions is of interest for studying migration pathways and the concentrations of elements in natural waters and for practical use of humiс substances as sorbents, as well as for environmental monitoring. In this work we studied the changes in the spectral luminescent properties and fluorescence kinetics of humic acids in water upon adding different concentrations of iron chloride, ammonium chloride and upon changing the pH of the solution. Conclusions about the influence of the humiс acids and iron concentrations, as well as the pH of the solution, on the interaction between ions of trivalent iron and humiс acids are drawn. |
