Description
Summary:<p>Development of the stripping voltammetric method for selective uric acid analysis through the glassy carbon (GC) and hanging mercury drop (HMD) electrode coating with molecular imprinting polymer (MIP) has been carried out.<br /> The polymer used as coating was synthesized from methacrylic acid (MAA) as monomer, ethylene glycol dimethacrylate (EGDMA) as cross-linker and uric acid as template at various molar ratios. The MIP for uric acid was obtained after extraction of uric acid from the polymer network. The resulted MIP was characterized by Fourier transform infrared (FTIR), scanning electron microscopy (SEM) and N2 adsorptiondesorption.<br /> The surface of electrode was coated with the polymer to give MIP-coated electrode at various time and potential. MIP-coated electrode was used as working electrode in voltammetry to determine uric acid concentration.<br /> Results show that the polymer has been successfully synthesized and the uric acid has been partially extracted from the framework. SEM images show that the surface of MIP had pores of &#61566
