Abstract	Norfloxacin (NOR) is a fluoroquinolone antibiotic commonly used to treat bacterial infections in humans. Detection of Norfloxacin (NOR)in this study was carried out Differential pulse voltammetry an electrochemical method at Glassy carbon electrode (GCE) . The voltammetric behavior of NOR was investigated in a suitable supporting electrolyte, and the effects of various experimental parameters such as scan rate, pulse amplitude, pulse frequency, pH were optimized. This electrochemical sensor shows excellent sensitivity and high selectivity for an electrochemical detection of NOR. The response is linear over the NOR concentration range of 〖1.5×10 〗^(-8) M to 〖1.0×10 〗^(-3) M, the LOD of 〖1.27×10 〗^(-9) M and LOQ of 〖3.84×10 〗^(-9)M. The developed DPV technique was successfully applied for quantitative detection of NOR in pharmaceutical formulations
