摘要：

Optimum conditions have been found for voltammetric determination of mutagenic 5-aminoquinoline, 6-aminoquinoline and 3-aminoquinoline by differential pulse voltammetry and adsorptive stripping differential pulse voltammetry on carbon paste electrode. The lowest limits of determination were found for adsorptive stripping differential pulse voltammetry in 0.1 mol dm(-3) H3PO4 (5 x 10(-7) mol dm(-3), 1 x 10(-7) mol dm(-3), and 1 x 10(-7) mol dm(-3) for 5-aminoquinoline, 6-arninoquinoline and 3-aminoquinoline, respectively). The possibility to determine mixtures of 8-aminoquinoline with 3-aminoquinoline or 5-aminoquinoline or 6-aminoquinoline, and mixtures of 5-aminoquinoline with 3-aminoquinoline or 6-aminoquinoline by differential pulse voltammetry was verified. Binary Mixtures of 8-aminoquinoline with 3-aminoquinoline or 6-aminoquinoline, and of 3-aminoquinoline with 5-aminoquinoline could be successfully analyzed.
