| Abstract: | Adsorptive stripping voltammetry at a hanging mercury drop electrode is described for various polarographically active compounds. Diazepam, nitrazepam, papaverine and aromatic nitro compounds can be determined at concentrations of 1 × 10?9–1 × 10?6 M with errors of 5–7%. The effects of changing accumulation potentials and times are considered. Interference by other surface-active agents may be removed by prior molecular exclusion chromatography. |
