The kinetics granules of boric acid (GBA) dissolution were investigated based on the solution temperature and stirring frequency. Experimental mass transfer coefficients were determined and compared with theoretical values. The results indicate that increasing the stirring frequency and the solvent temperature increases the mass transfer coefficient. A computational relationship was derived, enabling the prediction of GBA dissolution based on solution temperature and stirring frequency. These findings highlight the significant impact of reactor parameters and mixing conditions on the mass transfer process in solid-liquid systems. The study's results facilitate the simulation and optimization of mass transfer processes in solid-liquid systems, contributing to the optimization of chemical industry technological processes and reducing the energy consumption of the dissolution process.
