“…Other diazotization amine reagents tried were nonspecific, like NEDA, and/or produced colors too weak for the sensitivity of 0.2 ppm required. Other aniline reagents also examined were 9-chloroacridine (Stewart et al, 1969); KBrOs oxidation (Legradi, Laszlo, 1969); and 4-dimethylaminocinnamaldehyde (Tulus and Aydogan, 1967).…”

Vitavax (carboxin) is a systemic fungicide. This method determines 0.2 ppm (negligible residue) to 20 ppm in green forage crops including barley, cotton, oat, peanut, sorghum, and wheat plants; also potatoes and sugar beets. From 67 fortifications the average recovery is 89 %; the range 74 to 110%. Crop interference is 0.05 to 0.10 ppm. Aniline is liberated from Vitavax in NaOH solution and distilled. Hexane extraction removes inter-ference and the pH of the distillate is adjusted to 6.5 with H3PO4. The distillate is extracted with benzene.
