Title: Effect of simple anions and metal ions on the hydrolysis of disulfate ion

Abstract

This paper reports on the influence of anions and cations commonly found in flue gas scrubber systems on the hydrolysis rate of disulfate ion (S{sub 2}O{sub 7}{sup 2{minus}}) that has been studied. The cations studied include Na{sup +}, K{sup +} Ca{sup 2+}, Mg{sup 2+}, and Mn{sup 2+}. The anions studied include SO{sub 3}{sup 2{minus}}, SO{sub 4}{sup 2{minus}}, S{sub 2}O{sub 3}{sup 2{minus}}, S{sub 2}O{sub 6}{sup 2{minus}}, HSO{sub 3}{sup {minus}}, Cl{sup {minus}}, H{sub 2}PO{sub 4}{sup {minus}}, and HPO{sub 4}{sup 2{minus}}. Of the ions studied, Ca{sup 2+}, Mg{sup 2+}, SO{sub 3}{sup 2{minus}}, and S{sub 2}O{sub 6}{sup 2{minus}} were found to approximately double the rate of S{sub 2}O{sub 7}{sup 2{minus}} hydrolysis. Adipic acid was found to have no effect on S{sub 2}O{sub 7}{sup 2{minus}} hydrolysis. Activation energies for the S{sub 2}O{sub 7}{sup 2{minus}} hydrolysis rate accelerated by Ca{sup 2+}, Mg{sup 2+}, and SO{sub 3}{sup 2{minus}}, as well as for the unenhanced rate, were found to be in the range of 9-12 kcal/mol.
