However, no studies of the electrooxidation of these DNA nitrogenated bases on graphite electrode, modified with polymeric films derived from aminophenols, were found in the open literature.
The aim of this work was to investigate the electropolymerization of aminophenols onto graphite electrodes in more acidic media, as well as the electrochemical and morphological characterization of the modified electrodes produced and the immobilization of nitrogenated bases on these electrodes.
Voltammetric method has been reported for determination of aminophenols in a mixtures based on the oxidation peak potential difference between mA and oA and oA and pA using single- wall carbon nanotubes modified glassy carbon electrode .
and 1000, 250 and 100 ug ml -1 Al 3+ , Fe 2+ and Ca 2+ respectively did not interfere with the determination of aminophenols.
Keywords: HPSAM; Aminophenol isomers; NQS; Aqueous solution.
Aminophenol isomers are primarily used as intermediates in the manufacture of dyes and pigments.
Aminophenol isomers reacted with NQS reagent to give an orange color with Imax at 488 nm for oA and, red color with Imax at 535 nm for pA Schiff base in presence of CTAB (Figure1).
