Conteúdo: | The determination of imazaquin (2-[4,5-dihydro- 4-methyI-4-(I-methylethyl)-5-oxo-1 H-imidazoi-2-ilo]-3-quinolinacarboxylic acid) was carried out by cyclic voltammetry (CV) using carbon paste electrodes(CPE's) modified by 5 wt. % of polyaniline emeraldinc salt (CPE- PANI-ES) and emeraldine base (CPE-PANI-EB). The pH (2.5, 4.0 and 6.5) influence on electrode sensibility was studied. Cyclic voltammograms were obtained at scan rates of 20 mV.s-1 by scanning the potential between 0.6 and -0.9V, in sodium acetate 0.1mol.L-1 as supporting electrolyte. This determination was based on the influence or Imazaquin on the modified electrode.
