Is Geologic Mineral Trapping of Chlorine Plausible?
One strategy for sequestration of $\ce{CO2}$ is mineral trapping arising from geologic sequestration. Another strategy is mineral trapping in concrete via the Mineralization via Aqueous Precipitation or MAP process. In particular, Alkalinity Based…
