Abstract: PURPOSE: Disclosed is a control method of SO3- ion concentration for a wet desulfurization process using Mg(OH)2. CONSTITUTION: The concentration measurement of SO3 ion makes use of the principle that HSO3- ion and SO3- ion are presented in the constant equilibrium ratio under the constant pH and the reduction value of pH of HSO3- by the oxidation is solved the concentration of SO3 ion. The present invention uses hydrogen peroxide as the oxidant of HSO3-. The pH of probed reaction solution from the process is measured and HSO3- ion is completely oxidized by addition of a strong oxidant. And after measurement of pH, the ion concentration of HSO3- before oxidation is calculated.
