Versatile Platform for Spectrofluorimetric Determination of Some Chemical Drugs by Redox or Diazotization Reaction with Nitrite
Author(s): DAVID Vasile and DORE Mădălina
Nitrite and nitrate determinations received a special consideration in our research and more convenient analytical methods have been developed on this goal, based either on biamperometry1, spectrophotometry2 or fluorimetry3, coupled sometimes by flow injection1,2. However, the nonzero intercept of the biamperometric calibration obtained with the I2/I– redox system as indicating couple1, the perfect rectilinear response of the spectrophotometric method to the (nitrite + nitrate) molar sum as long as a photochemical reactor is coupled on-line2, and the easy development of the reaction between nitrite and proflavine in acidic conditions favoring the occurrence of a non-reactive tri-cationic species of the employed fluorimetric reagent3 reveal complex reaction... view more»
