    A composite of imprinted polypyrrole beads and reduced graphene oxide for specific electrochemical sensing of atrazine in complex matrices

  • Original language description

    Atrazine-imprinted reduced graphene oxide composite with its enhanced functionalities and porous surface was successfully synthesized and applied for the selective determination of atrazine in complex matrices. Scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, Fourier transform infrared spectroscopy, and X-ray diffraction studies revealed the imprinted polypyrrole beads formation on the reduced graphene oxide lining. Resultant composite was used to modify screen-printed electrode which then showed improved properties for voltammetric determination of atrazine. Measurements were carried out via square wave voltammetry giving a peak at - 0.9 V corresponding to the reduction of atrazine heterocyclic moiety. Obtained LOD and LOQ for atrazine were found to be 0.4 nmol/dm(3) and 1.2 nmol/dm(3), respectively, at optimized parameters. The method was applied for the atrazine determination in complex aqueous matrices.
