The study of humic acid interactions via ITC

There are various modelling systems including the Isothermal titration calorimetry to study interactions between ligand and molecule to describe the strength of bond with selected ligand acting in modelling system. Isothermal titration calorimetry is used to describe and characterize intermolecular interactions and recognition of reactions happening in studied system with excellent sensibility. It´s huge advantage is that it is possible to estimate the level of affinity of studied ligand to the substance. Major components of the organic matter in soil and water are humic substances. These compounds are basically organic polymers, therefore their complexity and structure reveal is needed, as their use and impact on soil quality is of huge interest. In the soil, these substances are highly chemically reactive with respect to biodegradation. There is also a huge impact on nutrients availability when these substances are presented in the soil used for harvesting variety of crops. The higher the importance of the presence of humic substances is revealed, the bigger effort is done to understand their behavior in the systems and to describe the humic substances with appropriate definable systems to obtain basic chemical experience describing the behavior of humic acids in the complex natural systems. This work discusses uses of ITC in humic research.
