Abstract

The binding of TNT to a soil and soil components is studied with 2H MAS NMR. This NMR technique clearly shows different interactions for deuterated TNT with soil, quartz, and clays. Basically, this NMR method relies on the Well-defined 2H MAS NMR characteristics of a deuterated methyl group attached to an aromatic ring. Stationary rings and rings executing 2- or 3-fold jump motions all yield different NMR spectra. The technique has good sensitivity; these studies were conducted at a TNT loading of 22 mmol/kg. For the soil sample studied, TNT showed binding similar to a TNT/K10-montmorillonite sample.
