原始语种摘要: Abstract(#br)The magnetite nanoparticles (Fe 3 O 4 ), synthesized by surfactant aided hydrolysis of the stoichiometric amounts of ferrous (Fe 2+ ) and ferric (Fe 3+ ) ions, were dispersed in carbon paste (CP) to fabricate magnetite modified carbon paste electrode (Fe 3 O 4 /CPE). The field emission scanning electron microscopy (FESEM) was used to evaluate the morphology of the synthesized powder in the pure phase and its distribution in the CP that revealed the well-dispersed Fe 3 O 4 nanoparticles in the graphite sheet with a mean size of 10nm. The microstructure analysis of the synthesized magnetite was performed by high-resolution transmission electron microscopy (HRTEM). The phase purity of the synthesized magnetite was evaluated by x-ray diffraction (XRD) analysis....
