AMPHOTERIC BEHAVIOR OF DI-2-PYRIDYL KETONE BENZOYLHYDRAZONE IN ETHANOL-WATER MIXTURES*
The ligand di-2-pyridyl ketone benzoylhydrazone (DPKBH) is widely used for the determination of transition metal ions in environmental samples. Due to its low solubility in water it is used in aqueous-ethanol (1:1) solvent and for higher sensitivity the pH must be properly adjusted. The properties o...
