Determination of Loxacin by Platinum Nanoparticles-Graphene Modified Electrode
A method for the determination ofloxacin(OFL)by PtNPs/Gr/GCE modified electrode prepared by depositing platinum nanoparticles(PtNPs)on the surface of glassy carbon electrode(GCE)modified with gra-phene(Gr)was established using multi-potential step method.The electrochemical behavior of OFL on the modi-fied electrode was studied.By optimizing the experimental conditions,the method had good linearity in the ran-ges of 0.75 μmol/L～50 μmol/L and 75 μmol/L～250 μmol/L.The detection limit was 0.02 μmol/L.Apply-ing PtNPs/Gr/GCE modified electrode in determining practical tap water and groundwater samples,the results were not detected.The spiked recoveries were from 95.3％to 102％,and the relative standard deviations were from 1.0％to 2.8％.
