Binding of chlorinated environmentally active chemicals to soil surfaces : Chromatographic measurements and quantum chemicalSimulations

Universität Rostock, 2014

Abstract: Adsorption studies of hexachlorobenzene (HCB) on the different well-characterized soil samples were performed. A new soil organic matter (SOM) model has been developed. Interaction of this model with HCB has been studied using different quantum-mechanical methods and molecular dynamics simulations. It has been explored that the alkylated aromatic, phenol, and lignin monomer compounds dominate the adsorption process. Moreover it was found that the most vital physical properties controlling this interaction are polarizability, molar volume, and charges of C atoms of the soil constituents.
