I am looking on calcium carbonate precipitation in seawater and would like to know how (or to what extent) anions (PO43-, CO32-, SO42-) and cations (Ca2+, Mg2+) draw water molecules into the calcium carbonate crystals lattice during precipitation. Also, how stable is the bonding between these ions and the water molecules?
Dear Lin, I have worked with oil production waters, which in some cases have chemical similarities to seawater. In particular the calculation of the ionic strength I have done taking care of all the stages of the chemical analysis, and when obtaining the chemical characterization I have used criteria of electroneutrality (Appelo, C. A. J. Geochemistry, groundwater and pollution/por CAJ Appelo y D. Postma.), in order to have sensible values of the incrustant tendency of the mineral species of interest, mainly calcite . I have not calculated the hydration energy, but I am interested in understanding the mechanisms of precipitation. Regards, Ender
what about ,thermal analysis techniques as the mass change of as function of temperature or time , just a suggestion
