The oxidation of Fe<SUP>2+</SUP> by ultrasound

With the help of Milliard's high frequency ultrasonic generator, type E-7562, with a barium titanate transducer with a frequency of 1 Mc, the oxidation of an acidic ferrous ammonium sulphate solution has been studied. The kinetics of the reaction, at six different concentrations of a ferrous ammonium sulphate solution and at four different ultrasonic intensities has been investigated. The reaction has been found to obey the first order kinetics. A probable mechanism based on the Haber-Weiss work has also been proposed
