| Abstract: |
| Calcite often dissolute and precipitate during groundwater transport, especially in uranium in-situ leaching with CO2+O2. Scholars study formation of calcite and determine boundary value of pH, which play a role in calcite occur. However, thermodynamics only characterizes the direction and probability of reaction without chemical reaction rate. Reaction kinetics is necessary studied to knowledge the fate of calcite in groundwater transport. Significant progress about reactive rate of calcite dissolution and precipitation as well as influence of water chemistry composition on reaction rate was summarized. It aims to study reaction kinetics of calcite and determine control effect and reactive rate, and provide theoretical basis for calcite clogging during uranium in-situ leaching with CO2+O2. |
