ac Polarography for tetracycline analysis.
The electrode processes for the reduction of several tetracyclines by ac polarography were examined. In pH 4.0 Walpole acetic acid-acetate buffer, two main waves occurred; the first was quasireversible and the second was reversible. Results showed that the first wave can readily be used for quantitative work. The second wave would also be suitable provided that there was no interference from other electroreducible substances.
