Enhancing the sensitivity and selectivity of salbutamol detection using reduced graphene oxide combined with molecularly imprinted polymers (RGO/MIP)

Abstract In this study, to enhance the selectivity and sensitivity of salbutamol detection performed by a carbon plate electrode, electrode was modified using novel molecularly imprinted polymer (MIP) combined with reduced graphene oxide (RGO). The RGO/MIP combination prepared polymerization methacrylic acid as monomer template. surface morphologies electrodes were studied field-emission scanning electron microscopy (FE-SEM), their performance tested an electrochemical technique that investigated both cyclic voltammetry (CV) amperometry (AMP) modes. compared MIP in which demonstrated have 4.16 nA/ppm sensitivity, more than 0.91 electrode. limit (LOD) 0.83 ppm, lower Moreover, electrode’s dynamic range extended from 1 1000 it exhibited consistency, repeatability, fast response, high for detection.
