The detection of ochratoxin A (OTA), a harmful toxic contaminant of foods causing serious health problems, is of great importance. Common analytical methods for this purpose are …
Understanding the dissociation of polyprotic acids in solution is important for many branches of chemistry and related sciences. A most important and at the same time knotty problem is …
The protolytic equilibrium of methyl ether of fluorescein is studied in water, aqueous ethanol, and in other solvents. The constants of the two-step dissociation are determined by …
Ionic equilibrium of 22 hydroxyxanthenes, including halogen and nitro derivatives of fluorescein, and their thio-and aza analogues, were studied spectrophotometrically in …
Within the course of this spectroscopic research, we revealed novel features of the protolytic behavior, which extend the knowledge of the chemistry of xanthene dyes and rationalize the …
