摘要: Abstract In this paper we report on the synthesis, characterization and use of monocarboxy-phthalocyanine-single walled carbon nanotube conjugates in electrocatalysis amitrole diuron. UV–Vis, FTIR XRD spectroscopies were used cobalt(II)-tris(benzyl-mercapto)-mono(carboxyphenoxy)-phthalocyanine (CoMCPc–PA-SWCNT(linked)), while AFM was to show changes surface morphologies modified electrodes. Cyclic voltammetry chronoamperometry for electrocatalytic oxidation diuron glassy electrode. The catalytic rate constants found be 1.83 × 10 6 1.99 × 10 M −1 s , respectively. linear range both 1.0 × 10 −5 –2.0 × 10 −4 M, with sensitivities 5.10 3.70 A mol L cm −2 diuron, limits detection estimated 0.14 0.20 μM respectively, using 3δ notation.
