The preparation, characterization and analytical application of a chemically modified gold electrode (CME), based on thiolated α-cyclodextrin self assembled monolayer (SAM), have been described. The CME was effective for the determination of nitroaromatic explosive compounds; 2,4,6-trinitrotoluene (TNT) was determined with satisfactory results (LOQ = 30 μm/L). The analytical response in contaminated water and in presence of other nitroaromatic compounds, such as 2,4-dinitrotoluene (DNT) and Picric Acid (PA), has been evaluated.

Abstract
The preparation, characterization and analytical application of a chemically modified gold electrode (CME), based on thiolated α-cyclodextrin self assembled monolayer (SAM), have been described. The CME was effective for the determination of nitroaromatic explosive compounds; 2,4,6-trinitrotoluene (TNT) was determined with satisfactory results (LOQ = 30 μm/L). The analytical response in contaminated water and in presence of other nitroaromatic compounds, such as 2,4-dinitrotoluene (DNT) and Picric Acid (PA), has been evaluated.File in questo prodotto:
