FEATURE IR SPECTRUM OF THE COMPLEX HUMIC ACID SAMPLES MYMIJO WITH METALS
We studied humic like acid complexing properties extracted from different preparations of natural object mumijo different geographical areas of origin: Altai, India, Kyrgyzstan. Complexing properties humic like acids are considered as an example of interaction with metals ecotoxicants such as Cu; Cd; Pb. By infrared spectroscopy with Fourier transform found differences in the IR spectra of humic like acids of various samples mumijo associated with metal ions. Based on the data, the comparative analysis found that under the influence of metals changes the spectral characteristics of humic like acids. The IR spectroscopy fixed displacement of the absorption bands characteristic of the bonds in carboxylic and phenolic groups, after the complexation noticeable difference in these groups from the original sample. Features of the effects caused by the change of supramolecular structures humic like acids in the formation of a complex with the metal ion.
