4. Conclusion
The electrochemical behavior of nitroxynil was studied in
buffered solutions at the mercury electrode surface using dc-polarography, cyclic voltammetry and controlled-potential elec-trolysis. Dc-polarography, differential-pulse stripping voltam-metry, and square-wave stripping voltammetry procedures were
optimized and successfully applied for quantification of nitrox-ynil in bulk form and its pharmaceutical formulation.
