Spectrophotometric investigation of the uranil(II)-hesperidin complex in 70% methanol
Апстракт
The composition and stability constant of the UO2(II)-hesperidin complex were determined by suitable spectrophotometric methods and pH-metric measurements. II was found that the uranil ion and hesperidin form a 1:2 complex in which the uranil ion is linked to the hesperidin molecule through the carbonyl and the 5-hydroxyl group. The relative stability constant, log K-2, ranged from 5.77 at pH 4.0 to 7.00 at pH 6.0. The conditions for the spectrophotometric determination of hesperidin, by means of reaction of the complex formation reaction, were investigated. Beer's law was obeyed up to 2.0x10(-5) mol dm(-3) hesperidin.
