POTENTIOMETRIC RESPONSE OF POLYMERIC LIQUID MEMBRANES BASED ON QUATERNARY AMMONIUM SALTS FOR NITRATE ION DETERMINATION

Perez, MDA; Yazdani-Pedram, M

Abstract

Polymeric liquid membranes are prepared using (3-nitro-o-xylene (NOX), tri-butylphosphate (TBP), bis-(2-ethylhexyl) sebacate (DOS), o-nitrophenyloctyl ether (o-NPOE), tris-2-ethylhexylphosphate (TEHP), dioctylphthalate (DOP) and dibutylphthalate (DBP) as plasticizers, and they have been used as sensors for nitrate ion, employing tri-octylmethyl ammonium chloride (TOMACl) as ionosphere and poly(vinyl chloride) (PVC) as matrix. The sensors showed Nernstian slopes with values of the practical detection limit (PDL) and lower limit of linear response (LLLR) in the concentration range of 10-6
