Abstract
Ultrasound is used to enhance the dissolution of lithium cobalt(III) oxide in the deep eutectic solvent choline chloride–sulfosalicylic acid by the mechanism of liquid stirring by acoustic flows and accelerated penetration of the liquid into the pores and cracks of a metal oxide. Formulas are derived to describe the kinetics of the process and establish the relationship between its main parameters and characteristics. The conditions for the most efficient use of ultrasound are identified. Experimental data are obtained on the dissolution kinetics of LiCoO2 powder in the deep eutectic solvent choline chloride–sulfosalicylic acid. The experimental data and the results of theoretical calculations are in good agreement, which confirms the adequacy of the developed ideas about the actual physicochemical essence of the studied processes.
