Mechanism of improving the rate of sono-oxidation of a KI solution by introduction of CO into an Ar atmosphere.

The rate of sono-oxidation of KI increased in a CO-Ar system compared to Ar alone. Higher values were obtained at 200 kHz with a maximum ratio of about forty. To determine the role of additional CO in the system, the effect of the pH of the reactant solution, the additional effect of NaHCO, sonoluminescence, and an analysis of products were examined.
