چکیده مقاله
A selective and sensitive electrochemical sensor was prepared by film coating of Cd II ion imprinted polymer IIP nanoparticle and Pyrenecarboxylic acid Py modified graphene Gr composite on glassy carbon electrode GCE The prepared electrochemical sensor was applied for the sensitive determination of Cd II ion by square wave anodic stripping voltammetry SWASV method The GCE/IIP Py Gr modified electrode showed improved electrochemical behavior as compared to bare GC electrode An optimum procedure was used for the fixation of Zn II 8 hydroxyquinoline to styrene ethylene dimethacrylate copolymer and the resultant IIP nanoparticles characterized by Fourier Transform Infrared FTIR , thermal gravimetric analysis TGA , and scanning electron microscopy SEM The effects of different experimental variables such as pH, deposition time, and deposition potential were optimized for electrochemical determinations The resultant IIP showed a selective sorbent for Cd II ion Py Gr was applied in construction of as prepared modified electrode, exhibits large surface area, enhanced electron transfer kinetics, and improved Cd II ion diffusion Under the optimal conditions, the resulting calibrationcurve exhibited a linear response within a concentration range of 5×10 12 to 15×10 8 mol/L 1 with excellentdetection limit 5×10 12mol/L 1 Finally, the method was successfully applied for the determination of Cd II ion in the tape water sample successfully, and the obtained results were verified by inductively coupled plasma ICP
