Abstract
CoFe2O4 nanostructures composed of spherical-like were obtained by sol-gel method with glucose as template and combine with MWCNT and composed CoFe2O4-MWCNT heterostructure. The crystal Structure, phase composition, morphology and magnetic properties of CoFe2O4/MWCNT heterostructure were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and vibrating sample magnetometers (VSM), A pure phase of well crystallized CoFe2O4 nanostructures, with average size of 60 nm, could be readily synthesized at present glucose. The modified glassy carbon (GC) electrode with CoFe2O4-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. © 2019 by CEE (Center of Excellence in Electrochemistry)
