METHOD OF INDICATING ENERGY DENSITY DISTRIBUTION IN ULTRASONIC FIELD IN LIQUID MEDIA

摘要

FIELD: chemistry.SUBSTANCE: invention is intended for qualitative estimation of ultrasonic energy density distribution in process volumes with an aqueous medium subjected to ultrasound. The invention is realised by adding an indicator in the form of a paper saturated with phenolphthalein to an alkalised aqueous medium. Energy density distribution in the ultrasonic field is estimated from the intensity distribution of the characteristic colour of the indicator paper which arises due to differences in the rate of diffusion of the solution into the indicator in areas of the field with different ultrasonic energy densities.EFFECT: facilitating a process of estimating energy density distribution in process volumes of ultrasonic apparatus using a method which is environmentally safe and safe for maintenance personnel.
