Effect of low-frequency ultrasound waves on the hydrogen peroxide degradation process

Abstract

Investigation of the activating effect of low-frequency ultrasonic waves on both fiber-forming polymer and chemicals and reagents used in bleaching processes of textile materials is an important objective. Comprehensive experimental studies on determination of the ratio of the treatment time and power of ultrasonic waves have been carried out in order to reach the optimal rate of hydrogen peroxide decomposition. The experimental results have shown that the optimal hydrogen peroxide degradation rate during ultrasoundassisted bleaching is observed at an ultrasonic power of 3 kW and a treatment time of 15–20 min.
