Electrochemical study of sulfadiazine on a novel phthalocyanine-containing chemically modified electrode

In this paper, cobalt tetraaminophthalocyanine (CoPc) was successfully deposited onto a carbon nanotubes modified electrode by consecutive cyclic scanning in supporting electrolyte containing CoPc to form phthalocyanine-containing chemically modified electrode. The electrochemistry of sulfadiazine was studied by voltammetric method and flow injection analysis at the new modified electrode. Compared with glassy carbon electrode, the new modified electrode exhibited exciting performance including low oxidation potential, high current response and promising flow injection response.
