    Preconcentration and electroanalysis of copper at glassy carbon electrode modified with poly(2-aminothiazole)
    (Gazi Univ, 2011) Ciftci, Hakan; Testereci, H. Nur; Oktem, Zeki
    Conducting poly(2-aminothiazole), PAT, was synthesized in acetonitrile with tetrabutylammonium tetrafluoroborate, TBAFB, as supporting electrolyte via constant potential electrolysis, CPE. Glassy carbon, GC, electrode was modified by immersing the electrode in a DMSO solution of PAT. Preconcentration of copper on polymer matrix was carried out at -0.7 V. The effects of preconcentration time and pH and Cu(II) concentration of the preconcentration solution on the stripping peak current of copper were studied.
