Abstract:
1. A process for making aqueous solutions of alkaline bicarbonates and/or alkaline earth bicarbonates comprising the steps of: dissolving gaseous carbon dioxide in water to produce an aqueous solution containing bicarbonates, HCO 3 − ; and further containing hydronium cations, H 3 O + , introducing a solid cationic exchanger material [(M x/n +n )E x − ] to capture the hydronium cations, H 3 O + and produce used cationic exchanger material [(H 3 O + ) x E x − ], according to: where “X” stands for a molar amount of anionic centers of charge of the cationic exchanger material [(M
