Abstract
The ability of the sorbent-mineralizer to irreversibly bind carbon dioxide in both fresh and sea water forming chemically and thermally stable carbonate structural forms based on melilite silicate Ca2[Al2Mg,Si]Si2O7 has been discovered. The latter is similar to natural minerals, therefore it is environmentally friendly. The influence of the chemical background of the sorbent-mineralizer on the process of its carbonization in aqueous media has been revealed. It has been shown that \({\text{CO}}_{3}^{{2 - }}\) groups in the composition of the initial sorbent-mineralizer are the primary active centers during the surface phase formation of carbonized calcium and magnesium aluminosilicates in aqueous media. It has been established that the thermal stability of the structure of carbonized calcium and magnesium aluminosilicates is maintained after heating to 1000°C. The formation of carbonized calcium and magnesium hydroaluminosilicates in seawater is accompanied by an increase in pH, which characterizes the ability of the sorbent-mineralizer to regulate the acid-base balance and maintain carbonate balance in the hydrosphere. In addition to the irreversible binding of CO2, the sorbent-mineralizer reveals the ability to irreversibly sorption of impurity cations Pb2+, Cu2+, Zn2+, as well as phosphorus in sea water.
