Popis:	Ultrasonic radiation from Mullard generator with barium titanate crystal as transducer having a frequency of 1 Mc/sec and power output 225 w/sq. cm. have been used to study the decolorization of aqueous solution of safranine O. Absorption curves obtained from spectrophotometric data demonstrate the fading of the colour of the dyestuff with the time of exposure. Diacetone alcohol, n-propyl alcohol, n-butyl alcohol, ethyl alcohol, dioxan and ether inhibit the decolorization. Hydrogen peroxide does not help the decolorization. Cavitation is responsible for breaking the molecules of the dye.
