Electrochemical Determination of Ciprofloxacin Using Glassy Carbon Electrode Modified with CoFe_2O_4-MWCNT

Cofe_2o_4 nanostructures composed of spherical-like were obtained by sol-gel method with glucose as template and combine with mwcnt and composed cofe_2o_4-mwcnt heterostructure. the crystal structure, phase composition, morphology and magnetic properties of cofe_2o_4/mwcnt heterostructure were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), and vibrating sample magnetometers (vsm), a pure phase of well crystallized cofe_2o_4 nanostructures, with average size of 60 nm, could be readily synthesized at present glucose. the modified glassy carbon (gc) electrode with cofe_2o_4-mwcnt heterostructure was used to determine the ciprofloxacin concentration. a cyclic voltammetric technique was used for comparison between the unmodified and modified electrodes. the fabricated modified electrode shows linear response for detection of ciprofloxacin at two linear range of 0.1-1 μm and 1-30 μm with a detection limit of 0.036 μm.
