Effects of Ultrasound Treatment and Dye Crystalline Properties on Particle Size Distribution

Abstract

The influence of ultrasound on changes in dye particle size and the specific breakage rate of disperse dyes with different crystalline properties are investigated. The resultsshow that ultrasound breaks larger dye particles suspended in water in their insoluble form into finer dye particles and reduces the mean particle size of disperse dyes. The specific breakage rate for dye particles irradiated by ultrasound depends on their crystalline properties, and the breakage rate of a well crystallized dye is higher than that of a poorly crystallized dye.

Breakage Characteristics of C. I. Disperse Red 60 Under an Ultrasound Field

“…Finally, when the vapor density within the microbubbles increases, cavitation damage is reduced, owing to the inhibition of microbubble growth and collapse, and also to a decrease in the collapse velocities. This overall mechanism is called the cavitation thermodynamic effect [ 1, 3,5]. When the liquid temperature increases, the dissolved air content, the viscosity, and the surface tension decrease, while the vapor density within the microbubbles increases.…”

“…In our previous work we reported that breakage of dye particles by ultrasonication depends on their crystalline properties [5]. Despite this ultrasonication study, there has been no systematic investigation of the breakage of dye particles by ultrasound.…”

Despite this ultrasonication study, there has been no systematic investigation of the breakage of dye particles by ultrasound. In this study, we investigate the characteristics of dye particle breakage by ultrasonication quantitatively by measuring the size of broken dye particles with a particle size analyzer.…”

Kinetic study of gelatin/chitosan based nanocomposites for acid red 150 dye adsorption using ultrasonic energy

“…Unexpected and burst breakdown of these bubbles could create centralize high pressure, high temperature, and stun waves [1,2]. The influence of ultrasonic application on the dye adsorption can emphases in terms of regular diffusion of the dye molecules in the fluid, accelerating of the dispersion rate of dye within the composite and enhancing the reaction between composite and dye [3][4][5][6][7][8][9][10][11]. Recently, some attempts have been made to prepared and investigate novel nanocomposites for adsorption of some toxic materials.…”
