  • Abstract
    Highly selective and sensitive method for the kinetic spectrophothometrith determination of sub-microgram amounts of nitrite has been development based d on its reaction with Nile blue 2B in acidic medium. The reaction is monitoreerd spectrophotocometrically at 595 nm at a fixed time of 4.5 min. The change in absorbance at 595 nm is related to the concentration of nitrite in the ranange 0.005 - 1.100 Mg.ml**-1. The detection limit is 0.001 Mg.ml**-1. The relalation standard deviation is 1,for 0.020 mg.ml**-1. The relation standard deviation is 1,for 0.020 Mg.ml**-1 of nitrite for ten replicate measurements. MMost common anions and cations do not interfere. The procedure was applied to the determination of trace amounts of nitrite in sausage and water.
