Voltammetric determination of pharmaceuticals at the tubular graphite electrode
ANALYSTANALYST Pub Date: DOI: 10.1039/AN9800500779
Abstract
Many pharmaceuticals, including phenothiazines, sulpha drugs, purines, phenolic acids, local anaesthetics and antifertility compounds, have been determined quantitatively by oxidative voltammetry at the tubular graphite electrode under hydrodynamic conditions. The data obtained fully establish the reliability of the technique for the determination of these compounds with ease, precision and speed.
A simple empirical correlation that permits the direct determination of the concentration of any unknown electroactive substance in one stage without using a standard reference solution has been derived and verified.
