摘要: This paper presents a simple model for the study of dissolution calcite and precipitation gypsum in acidic solutions. The numerical predictions calcium hydroxyl ion concentration have been used to develop approximate analytical expressions growth rate solution, ions concentration. These turn determine evolution kinetic constants, make that show good agreement with experimental data.
