A new,simple and convenient method was proposed to determine FLRX.Cyclic voltammetric behavior of Fleroxacin(FLRX) on graphite electrode was studied.FLRX can be strongly adsorbed on graphite electrode.At the potential of +1.040V(vs.SCE),FLRX is oxidized and adsorbed on the electrode surface.Using HAc~NaAc as a buffer solution, FLRX showed a reduction wave and the peak potential of -0.110V(vs.SCE) by linear sweep voltammetry after the electrode was washed by double distilled water.A new method for the determination of FLRX was established by adsorptive transfer stripping voltammetry.The peak current is proportional to the concentration of fleroxacin in the range of 4~42 μ g/mL.The method is simple,sensitive,fairly free of interference and accurate. 展开更多
