Voltammetric determination of 4-aminopyridine
Kudláčková, Kateřina ; Zima, Jiří (advisor) ; Fischer, Jan (referee)
In this thesis, the voltammetric behavior of 4-aminopyridine was investigated using carbon paste electrode. Differential pulse voltammetry was used for the study. Measurements were carried out in Britton-Robinson butter medium with different pH values. Optimal pH value found was 9. The electrode passivation during consecutive measurements of 4-aminopyridine without the surface renewal was confirmed, while the accumulation time had no influence on peak heights of 4-aminopyridine. Limit of detection was 8,76×10-6 mol dm-3 and limit of quantification was 1,85×10-5 mol dm-3 of 4-aminopyridne under optimal conditions. The linearity of the calibration curve was evaluated using the correlation coefficient.
