Kinetic analysis of retention of SO2 using waste ulexite ore in an aqueous medium

A kinetic evaluation, performed with the retention-dissolution data using kinetic models for heterogenous reactions, found that the kinetics model for SO2 retention fitted diffusion through product layer control. In addition, the kinetics model for the B2O3 dissolution fitted the diffusion through product film control. Activation energies for SO2 retention in solid waste and B2O3 dissolution were 6196 J mol−1 and 15436 J mol−1 respectively.
