Effects of Soluble Ions on the Hydration of Calcined Flue Gas Desulphurization (FGD) Gypsum

Abstract: The influence of various water soluble ions on the hydration of calcined flue gas desulphurization gypsum was investigated. The presence of K+ can significantly increase the solubility of gypsum through the precipitation of K2SO4. All cations were found to accelerate the hydration of basanite, where Ca2+ shows the weakest acceleration effect. The final crystal size is not largely influenced by different salts, except for Na+, where the giant crystal with length of >130μm is observed. Current study clarifies the influence of different ions on the hydration of basanite, which could provide sufficient guide for the pre-treatment of original flue gas desulphurization gypsum before actual application.
