摘要：

The cyclic voltammetric behavior of nitrazepam was investigated at screen-printed carbon electrodes over the range -1.5 V to +1.5 V. Two reduction peaks were observable oil the negative scan, at -0.7 V, and -1.2 V using pH 6 buffer. On the return scan a single oxidation peak was obtained at -0.05 V. For quantitative analysis of beverages, we developed an anodic adsorptive stripping voltammetric method which required only dilution with buffer. The identification of nitrazepam and flunitrazepam could be achieved using cyclic voltammetry.
