Özet:

 


This paper examined use of a boron doped diamond
electrode (BDDE) for the electroanalysis of ofloxacin (one of the fluoroquinolone compounds) by
cyclic voltammetry (CV) and square wave voltammetry (SWV) in the presence of
anionic surfactant (SDS) for the first time. The current signal due to the
oxidation process was a function of the amount of ofloxacin, pH of the medium, effect
of anionic surfactant (sodium dodecyl sulfate) and scan rate. Cyclic voltammetric studies indicated an irreversible
behaviour of ofloxacin in phosphate buffer solution at pH 2.0 with well-defined
oxidation peak at +1.24 V (absence SDS) and +1.21 V (presence of SDS) vs. Ag/AgCl,
respectively.  With optimized
experimental parameters, the current response of ofloxacin was proportionally
linear in the concentration range from 1.0×10-7 to 3.5×10-6 M. A
detection limit of 1.76×10-8 M
was observed anodically electrochemical surface pretreatments. The practical applicability of the developed method
was demonstrated on the determination of ofloxacin in human urine and
pharmaceutical samples. In
this way, BDD electrode may represent an efficient alternative to widely used
modified electrodes in the determination of fluoroquinolone
compounds.
