Carbonation

Felipe MacíasMarta Camps-Arbestain, in Advances in Agronomy, 2020. Carbonation (pH 7.5–9.0): The increase in the concentration of carbonate ions leads to the saturation of the system with CaCO 3 with subsequent precipitation of CaCO 3 (equilibrium pH 8.2) and other carbonates (e.g., with Mg, Na) at higher pH values. While this is not a weathering reaction per-se, the presence of CaCO 3 in ...

Molecules | Free Full-Text | Investigating the Fluid–Solid ...

The subject of rock–fluid interaction is important in cases where flow through porous media is occurring. One special case is when the fluid reacts with the porous matrix. In this case, the mass transfer and reaction rate control the dissolution pattern. This article aimed to study the interaction between an acid nanoemulsion system and a carbonate porous media.
