Effect of Flow Rate on Sonochemical Efficiency in the Continuous Flow Sonoreactors

Abstract

The sonochemical efficiency in the continuous flow sonochemical reactor with the maximum volume of 3.9 dm³ was investigated as a function of flow rate. The sonochemical efficiency was estimated by the oxidation in aqueous solution of 0.1 mol·dm^-3 potassium iodide (KI). We estimated the apparent rate constant of production of I₃^- on the basis of the traditional modeling equation of the pipe flow reactor. The reaction rate increased with increasing flow rate but saturate at the flow rate larger than 10 dm³·h^-1.
