title: Determination of nitrite using sensors based on nickel phthalocyanine polymer modified electrodes.
abstract: An amperometric nitrite sensor based on a polymeric nikel tetraaminothphalocyanine (p-NiTAPc) film coated glassy carbon (GC) electrode was developed. The mechanism of catalysis on the surface of the electrode was discussed. The sensor exhibited fast respond towards nitrite with a detection limit of 1x10(-7)M and a linear concentration range of 5x10(-7) to 8x10(-3)M. The possible interference from several common ions was tested. The proposed method was successfully applied in the detection of nitrite in real samples.
