【摘要】 诺氟沙星在０．０５ｍｏｌ·Ｌ－１ＮＨ４Ｃｌ（ｐＨ５．８）溶液中，出现一灵敏的示波极谱还原峰。峰电位为－１．４４Ｖ（ｖｓＳＣＥ）。峰高与诺氟沙星的浓度在１．０×１０－７～４．０×１０－６ｍｏｌ·Ｌ－１范围内成正比，检出限为５．０×１０－８ｍｏｌ·Ｌ－１，并用于样品的测定。用线性扫描与循环伏安法等手段研究体系的吸附性质。实验表明，该电极过程为具有吸附性的不可逆过程。更多还原

【Abstract】 In 0. 05 mol · L-1 NH4Cl solution, a sensitive teduction wave of norfloxacin is obtainedby single-sweep cacillopolarography. The peak potential is - 1. 44 V (vs SCE). The peak height isproportional to the coneentration of norfloxacin over the range of 1 . 0 × 1 0-7～ 4. 0 × 10-6 mol · L-1 . Thedetection limit is 5.0× 10-8 mol · L-1. The methed has been applied to the determination of norfloxacin.The adserptive characteristiee of the system has been studied by means of lincar sweep and cyclicvultammetry, NPP, etc. . The eleetrede reduction procesa is irreversible with adsorptive characteristics.更多还原
