In this research, NaX nanozeolite was synthesized via an organic template-free hydrothermal route and characterized by X-ray diffraction technique. The average particle size of synthesized NaX nanozeolite was estimated to be 52 nm using Debye–Scherrer equation. Carbon paste electrode (CPE) was modified by synthesized NaX nanozeolite and then Ni2+ ions incorporated to this electrode to obtain Ni¬¬-NaX/CPE. The current intensity of gentamicin oxidation increases impressively on the surface of Ni¬¬-NaX/CPE. This fabricated electrode was used as an anode for the electrocatalytic oxidation of gentamicin in 0.1 M of NaOH solution. It has been shown that NaX nanozeolite at the surface of CPE can improve catalytic efficiency of the dispersed nickel ions toward oxidation of gentamicin. It was experimentally determined that higher anodic current of gentamicin oxidation is observed when 10% of NaX was used with respect to the graphite powder.
