| Abstract: | The influence of various cations on the reaction of urea with diacetylmonoxime and phenazone was studied. Fe3+ and Ce4+ appeared to increase sharply the reaction rate.The accelerated reaction could be conveniently performed with an autoanalyzer. In comparison with other methods used with this apparatus, the reaction described presents the advantage of highly increased sensitivity and of a less drastic reagent. It possesses good reproducibility and a wide range of validity. |
