摘要：

The dissolution of calcite under conditions of high pH (8.0-9.0) is shown to be strongly inhibited by the presence of magnesium (Mg2+) cations. Channel flow cell measurements are used to deduce the appropriate rate law for dissolution and it is demonstrated that the inhibition arises from competitive Langmuirian adsorption of Mg2+ and Ca2+ ions on the calcite surface.
