| Description |
Voltammetric responses of trifluoroacetic acid,
perfluorobutyric acid, perfluorohexanoic acid, and perfluorooctanoic
acid (PFOA) were studied in acetonitrile/tetra-nbutylammonium
perchlorate medium on glassy carbon
electrode. All the four acids gave two voltammetric waves.
PFOA exhibits blocking effects. In the presence of excess
water, the first cathodic peak current increases, and the
second peak disappeared. Very small quantity of triethylamine
(TEA; 1–2 mM) was found to be effective in
suppressing the first cathodic peak. Both the peak current
and peak potential values were sensitive to water and TEA
content. The ester derivatives of all the four perfluorocarboxylic
acids (PFCAs), however, gave well-defined
cathodic reduction peak around −2.3 V. This peak appears
to be the best choice for quantitative estimation of PFCAs.
