Abstract | dc.description.abstract | An ion selective electrode for nitrate, composed of 2-[5-(4-nitrophenyl)furyl]-4,5-diphenyl imidazole as ionophore and dioctylphthalate (DOP) as plasticizers in poly[vynil chloride] (PVC) supported on a conducting resin, is described. The sensor exhibit Nernstian response toward nitrate with a slope of-63,97 mv/decade, practical detection limit (PDL) of 2,07491 · 10-6 MOL/dm3, lower limit of linear response (LLLR) of 4,62785 · 10-6 mol/dm3 and with a response time of <20s. Chlorine, bromine and iodine presented considerable levels of interference with values of K Pot AB of 1,97956 · 10-4, 1,85562 · 10-3 and 9,78836 · 10-2, respectively. | en_US |
