Notes: High frequency ultrasonic waves of frequency 1 Mc/s. have been employed to study the decolourization of dilute aqueous solution of crystal violet. The process is irreversible and the kinetic study shows it to be unimolecular one. The deaeration of the solution by nitrogen does not affect the rate of the decolourization. The addition of certain substances such as alcohol, acetone, ether, glycerine, dioxan and allylthiourea inhibits the decolourization to a considerable extent. Oxidation and subsequent destruction of the dye molecule has been found to be the cause of the fading of the dye solution.
