Abstract

The protonation constants of tannins and its coordination compounds stability constants were studied by equilibrium pH method at 20癈 and constant ionic strength. The result shows the distribution diagram of ligands of tannins respectively. In the same way, the protonation constants and stability constants of three kinds of models about phenol, catechol and pyrogallol were determined.
