Synthesis and Evaluation of Nano Zeolite Na/Al as a New Modifier for Electrochemical Determination of Acetaminophen

In this study, a new Zeolite Al/Na (ZAN) was synthesized and characterized and then a new modified Carbon Paste Electrode with ZAN was made to determine Acetaminophen. Electrochemical studies using Linear Sweep Voltammetry and differential pulse voltammetry were used to determine electrochemical  Acetaminophen . In the presence of Acetaminophen , modified electrode with ZAN shows a specific anodic peak at ~ ۰.۵۹ volts which is the result of using electrocatalytic oxidation of  Acetaminophen . The determination limit of this method to measure  Acetaminophen was ۵.۸ µM, the relative standard deviation for ۷ repeated measurements was ۱.۱ % and linear range of the calibration to measure  Acetaminophen was ۱۰ up to ۱۱۵ µM . for the characterization of ZAN nanostructures we used SEM (Scanning Electron Microscopy), DLS (Dynamic Light Scattering) and FT-IR (Fourier-Transform Infrared spectroscopy).
