Precipitation of calcium carbonate in a calcium nitrate and monoethanolamine solution

High-purity precipitated calcium carbonate has been produced in the laboratory by carbonation of a solution of calcium nitrate and monoethanolamine. The process was traced by measurements of the change in Ca concentration and in electrical conductivity of the solution. The κ− t and c Cu− t curves we...

Description
Summary:High-purity precipitated calcium carbonate has been produced in the laboratory by carbonation of a solution of calcium nitrate and monoethanolamine. The process was traced by measurements of the change in Ca concentration and in electrical conductivity of the solution. The κ− t and c Cu− t curves were analyzed to determine the effect of temperature and concentration of carbon(IV) oxide on the process of carbonation. The samples obtained were mainly of aragonite and vaterite crystal modifications with traces of calcite. The relationship between the mineralogical composition and particle size (morphology) and operating conditions was examined as well.
