Models for complexation of humic compounds
Věžníková, Kateřina ; Jaroslav,, Záhora (referee) ; Klučáková, Martina (advisor)
This bachelors thesis deals with interactions of copper ions with humic acids. The bond between metal ions and humic acids is formed mainly trough carboxylic and phenolic groups. Mechanism of these interactions is not so far enlighted. Essential part in this, is reality that humic acids are not chemical individuals, but polydisperse mixtures of substances. This work contains interactions of metal ions with model compounds like citric acid, salicylic acid, pthalic acid, hydroquinone, catechol and EDTA, which simulates possible binding sites in the structure of humic acids. Several analytical methods have been used to study this problems: potentiometry (pH), conductometry and UV/VIS spectroscopy. As a model metal ion has been chosen copper cation because of its high afinity to humic acids.
