    Abstract:
    Seawater flue gas desulfurization (Seawater FGD) process has a number of advantages, but the study on mechanism of seawater FGD is little. The effects of absorbing efficiency of SO2 by the constant component and part of trace transition elements in seawater are studied by the experiment. The results indicate that the effect factors of absorption of SO% by seawater are alkaline, ion intensity, catalysis of Cl- and transition metal ions Fe2+ Mn(2+). The degree of effect is alkaline > the catalysis of Cl-, Fe2+ and Mn2+ > ion intensity. The mechanisms of catalysis oxidation for S( IV) by Cl -, Fe2+ and Mn2 are discussed. According to the results, some measures can be used to improve the capability of desulfurization.
