Role of Donor-Acceptor Interactions in the Sorption of TNT and OtherNitroaromatics from Solution

摘要

The evidence related to sorptive interactions of nitroaromatics is reviewed.Although evidence from a variety of organic model systems suggests that sorptive interaction of nitroaromatics with organic components will occur, the statistical evidence attributes greater importance of inorganic components over organic matter in soil sorption of TNT. It was concluded that donor-acceptor interactions are more important than purely hydrophobic effects in the sorption of nitroaromatics from solution onto soils and model sorbents. Furthermore, TNT in soil-water systems may become an ultimate recipient of charge, causing its reductive transformation and subsequent covalent bonding to soil organic matter components.
