M. Aliskandarani et al., IDENTIFICATION AND DOSAGE OF URACIL AND 5 -HALOGENOURACIL IN SOLUTIONBY UV-SPECTROMETRY AND HPLC, Analusis, 23(1), 1995, pp. 17-22
Successive deprotonations of uracil and 5-halogenouracils are displaye
d in a wide pH range (6 < pH < 16). The conditional stability constant
s and the molar absorbance of each protonated form have been determine
d by simultaneous and spectrometric UV measurements. Besides, high per
formance liquid chromatography (HPLC) allowed investigation of uracil
chlorination by sodium hypochlorite solution in determined conditions.
Advantages and disadvantages of both techniques are discussed and a c
omparison made in terms of species detection.
