ELECTROANALYTICAL CHARACTERISTICS OF OFLOXACIN IN MICELLAR SOLUTION

In a pH 6.30 buffer solution containing 0.001% Tween-80,ofloxacin(OFX)gives a sensitive polarographic wave at-1.46 V(vs SCE),which can be used for the determinationof OFX downto 10^-8mol·L^-1.The linearrange is from 1.39×l0^-7 to 1.39×10^-5 mol·L^-1.Theproposed method was applied to detennination of OFX in urine and serum samples with relativestandard deviation less than 7.0%.
