dc.description.abstractThe complex [TpPh,MeNi(Cl)PzPh,MeH] (I) [Tp Ph,Me=hydrotris(3-phenyl-5-methyl-pyrazol-1-yl)borate; Pz Ph,MeH=3-phenyl-5-methyl-pyrazole] has been synthesized and explored as ionophore for the preparation of a poly(vinyl chloride) (PVC) membrane sensor for benzoate anions. The formation constants for the interaction of complex I with different organic/inorganic anions in solution have also been studied by sandwich membrane method. PVC based membranes of I using tridodecylmethylammonium chloride (TDDMACl) as cation discriminator and o-nitrophenyloctyl ether (o-NPOE), dibutylphthalate (DBP), benzylacetate (BA) and tributylphosphate (TBP) as plasticizing solvent mediators were prepared and investigated as benzoate selective sensors. The best performance was shown by the membrane with composition (w/w) of I (5): PVC (150): NPOE (345): TDDMACl (0.3). The proposed sensor exhibits significantly enhanced selectivity toward benzoate ions over the concentration range 2.2 × 10-6 - 1.0 × 10-1 M with a lower detection limit of 1.4 × 10 -6 M and a Nernstian slope of 59.2 mVdecade-1 of activity within a pH range of 4.5-8.5. The sensor has a response time of 12 s and can be used for at least 8 weeks without any considerable divergence in their potential response. The membrane sensor of complex I have been checked for reversible and accurate sensing of benzoate levels present in liquid food products. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.-
