Results of sorption experiments considering an initial water-CO₂ equilibrium . a,b) Zinc concentration evolution as a function of time for experiments performed with the Lavoux and the St-Emilion carbonate in aqueous (empty symbols) and saline solution (full black symbols): [Zn(II)]_i equal to 10⁻⁴ M (full line), 10⁻⁵ M (dotted line), 10⁻⁶ M (dashed line). c,d) Evolution with time of [Mn(II)]. The same code as for plots a) and b) is used. When not visible, error bars are comprised within the symbol size. e,f) Evolution with time of [Sr(II)]. The same code as for plots a) and b) is used. When not visible, error bars are comprised within the symbol size.
