Fabrication of electrochemical sensor for determination of Cholorophenillamin based on CQD/ZIF-۹۰/PVP

The research is aimed at investigating the electrochemical behavior of chlorpheniramine by the cyclic voltammetric method in real samples on the surface of carbon paste electrode (CPE CQD) modified with carbon quantum dot /metal-organic framework/polymer (CQD/ZIF-۹۰/PVP).Carbon quantum dot particles were synthesized by hydrothermal method. ZIF-۹۰ and PVP were used as surface modifiers to improve the properties of CQD nanoparticles, such as surface area-to-volume ratio, adsorption capacity, hydrophobic interactions, and selectivity.The accuracy of the synthesis method, the FT-IR infrared spectroscopy to identify, and SEM scanning electron microscopy and X-ray diffraction XRD tests, were used for morphology.CQD/ZIF-۹۰/PVP nanocomposite were examined by the oxidation method to synthesize and final properties by the EDX test.The result of the test show synthesizes dispersed phase particles in the matrix Pransh better and better properties of nanocomposite with the metal-organic framework/polymer showed.The pharmaceutical measurement steps were performed with the modified carbon paste electrode by the cyclic voltammetric method.
