Adsorption of oxalate seed poisons and its effect on crystallization

Summary

This study was part of a three-year project designed to characterize the adsorption of oxalate seed poisons (OSP) onto sodium oxalate, and the effect of such adsorption on oxalate nucleation, crystallization and thickening.

The effects of OSP were quantified, and a mechanistic understanding of their action was sought.
