摘要：Poly(2-methoxyaniline) microspheres (P2MA) were prepared by oxidative polymerization method usingpotassium persulphate and β-naphthalenesulphonic acid (NSA) as an oxidizing agent and dopant respectively. Thespectral, morphological, and electrochemical characteristics of P2MA microspheres were determined from the resultsof Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, UV-Vis spectroscopy, scanning electronmicroscopy (SEM) and cyclic voltammetry (CV). The electrochemical sensing property of P2MA microspheres werestudied by CV and chronoamperometry (CA) using uric acid (UA) as an analyte. The calibration curve for UA wasobtained over the range of 6.6 to 62.5 μM with corresponding sensitivity of 0.003 μAμM-1. The proposed sensor issimple, easy and cost effective which will have a great potential in electrochemical biosensor.
