Organic Electroanalysis with Chemically Modified Electrodes

Abstract
The analytical utility of electrodes modified with functionalized polymer films for the determination of aromatic amines is demonstrated. The analysis is based on the preconcentration of the protonated amines into a functionalized polymer film that contains styrene sulfonate groups. Good sensitivity and high reproducibility were obtained for concentrations down to 10−5 M. Aliphatic amines do not interfere in the determination.
