METHODS FOR REMOVING CARBONDIOXIDE AND CONTROLLING CRYSTAL STRUCTURES OF CALCIUM CARBONATE

摘要

This invention relates to a method of removing carbon dioxide through production of calcium carbonate by hydrating carbon dioxide and precipitating calcium carbonate, and to a method of controlling precipitation of calcium carbonate using a basic buffer upon hydration. In a process of precipitating calcium carbonate, the type of buffer is controlled upon hydration of carbon dioxide, thus controlling the morphology of precipitated calcium carbonate. Through the process of precipitating calcium carbonate, a basic buffer is adjusted, thus variously controlling the morphology of precipitated calcium carbonate.
