KINETIC-SPECTROPHOTOMETRIC DETERMINATION OF TRACE AMOUNTS OF NITRITE BY THE REACTION OF METHYL ORANGE FORMATION

نویسندگان: ثبت نشده
چکیده مقاله:

The composite diazotization coupling reaction of sulfanilic acid and N, Ndimethylaniline was used for the precise, accurate, and rapid determination of trace amounts of nitrite ion (0.02-3 µg/ml). The reaction was monitored spectrophotometrically by measuring the absorbance of the produced methyl orange at 510 nm by a fixed the method of 5.0 minutes. The relative standard deviation for the determination of 0.50 µg/ml of nitrite was 1.8% (n=l 1). The method was used for the determination of nitrite in sausage and water samples
