Abstract: Solutions of both basic and acidic dyes were subject
to sonolysis, electrolysis, and sonoelectrolysis. Only basic dyes were
decolorized by ultrasound alone. Removal of the acidic dye Sandolan
Yellow required the use of an electrooxidation process. The rate of
electrochemical decolorization in the absence of ultrasound was dependent
on the type of electrolyte, the electrolyte concentration, the reaction
temperature, and the current density. The sonoelectrooxidation of Sandalon
Yellow needed to be performed in a sealed cell to minimize the effects
of ultrasonic degassing.
