CATHODIC STRIPPING VOLTAMMETRY OF THE ANTIBACTERIAL DRUG (NITROFURANTOIN)

Cathodic stripping voltammetry was used to determine the antibacterial drug Nitrofurantoin in phosphate buffer (pH 5.5). The adsorptive peak was observed at -0.173 V vs. Ag/AgCl. The peak response was character ized with respect to pH, preconcetration time, possible interferences, deposition potential, supporting electrolytes and other variables. Th e obtained results were analyzed and the statistical parameters were c alculated Also the method was applied to determine the mentioned lug i n pharmaceutical formulations and urine. The limit of detection was 1x 10(-9) mol dm(-3).
