From that solution you could precipitate calcium carbonate by adding Na2CO3, via the following reaction: Na2CO3(s) + CaCl2(s) + H2O(l) ⤑ …
Typical sequential extraction protocols were developed to extract from low-carbonate samples and therefore are not necessarily suitable for high-carbonate …
This study aims to investigate the effects of the strength improvement of soft ground (sand) by producing calcium carbonate powder through microbial reactions. To analyze the cementation effect...
The process captures CO 2 directly from a gas stream and transforms it to solid calcium carbonate. The dependence of the Ca extraction efficiency on the slag …
was to develop a sequential extraction procedure for carbonate-rich samples that guarantees the quanti-tative dissolution of calcium carbonate in a discrete carbonate …
The main objective of our study was to develop a sequential extraction procedure for carbonate-rich samples that guarantees the quantitative dissolution of calcium carbonate in a discrete carbonate-removal step.
About 3% of calcium in the concrete sludge could be extracted into the filtrate in a single filtration step, and more than 95% of dissolved calcium was recovered as calcium carbonate by the …
Production of precipitated calcium carbonate (PCC) via carbon dioxide (CO 2) pressure-swing mineral carbonation is a potential way to utilise calcium-rich steel slag and carbon dioxide. Calcium supersaturation …
