Nucleation and growth kinetics of CaCO3 crystals in the presence of foreign monovalent ions

The aim of this work is to study the effect presence different monovalent ions (Na+, NH4+ and K+) on nucleation growth rates CaCO3 precipitation. There currently great interest in precipitation particles reusing CO2 rich flue gases calcium-rich wastes, which implies foreign that can affect crystallization process. Unseeded seeded tests were carried out a batch system estimate kinetics, respectively. Tests with Na2CO3 CaCl2 as precursors led classical calcite mechanism via vaterite formation at high supersaturations. On other hand, use (NH4)2CO3 entailed lower pH NH4+, stabilized avoided its transformation into stable crystals. Thus, faster kinetics by using obtained. To rate, two initial seed loadings types (micro nano seed) performed. rate increased crystal size decreased magma density. results indicate ion seems be related ionic radius ion.
