Studies on Pollutants: Spectrophotometric Determination of Nitrile as "Azoxine Dye"
Ten new reagent systems for determination of nitrile in water have been studied.A new system for the determination of nitrile using diazotised aromatic amine with 8-hydroxyquinoline as a coupling reagent has been developed.Sulphanilide was found to be most suited out of the ten amines tried for the determination of nitrite.The λmax of the dye is 500 nm.The Beer's law is followed in the range of 4-30 μg of nitrite per 25 ml.The molar absorptivity and Sandell's sensitivity are 30 x 1E3 litre mole-1 cm-1 and 0.0015 μg cm-3 respectively.The optimum reaction conditions and other analytical parameters such as, Beer's law, sen sitivity and interferences due to foreign species have been studied.
