Ultrasonic mineralization of a reactive textile azo dye, Remazol black B

[摘要] The degradation of a reactive black dye in oxygen saturated aqueous solution has been investigated using a high frequency ultrasonic generator. The (OH)-O-. radical initiated oxidative degradation of the dye results in 65% mineralization as measured by the decrease in the total organic content. Ion chromatography indicates that the only remaining components are oxalate, sulfate and nitrate ions. (C) 1998 Elsevier Science Ltd. All rights reserved.
