Název v původním jazyce

Comparison of complexation properties of humic acids and simple organic ligands

Popis výsledku v původním jazyce

Simple organic compounds as citric acid, phthalic acid, salicylic acid, EDTA, hydroquinone and pyrocatechol were used as structural models of active sites of humic acids. Combination of high resolution ultrasound spectrometry with potentiometry, conductometry and UV/VIS spectrometry were utilized for complexation of copper(II) ions by humic acids and model compounds. Changes in the slope of measured quantities were used to find the saturation of binding. Ultrasound spectrometry showed follow changes ofhydration of interacting species. The differences observed for individual model compounds show that there are active centres not only with various strength and stability of formed complexes but also with their various rigidity and ability of conformational changes.
