Determination Des Constantes D'Ionisation De Quelques Orthodumines Aromatiques

Abstract
Ultra-violet and visible absorption spectra of some aromatic orthodiamines were studied, and their ionization constants determined (Ionic strength: 2. 0 M; 25° C). A new computer method (“complex” method) was used for either the resolution of one overlap of pKa or the correction of the medium effect.
