Abstract

Complex solution chemistry associated with formation and growth of hydrous chromium(III) oxide particles of narrow size distribution was investigated. The sols were prepared by heating dilute solutions of chromium(III) salts in the presence of sulfate ions. Upon removal of sol particles by filtration, complex solute species present in the electrolyte medium were separated and characterized using radio-paper electrophoresis. The results indicate that two solute species are involved in solid formation, and that multi-component equilibria are established. The effects of anion concentration and temperature are also discussed.
