A thermodynamic solution model for calcium carbonate: Towards an understanding of multi-equilibria precipitation pathways

摘要: Thermodynamic solubility calculations are normally only related to thermodynamic equilibria in solution. In this paper, we extend the use of such help elucidate possible precipitation reaction pathways during entire reaction. We also estimate interfacial energy particles using data by a modification Mersmann’s approach. have carried out considering reactions as succession small quasi-equilibrium states. Thus equilibrium can be evaluated calculating evolution surface charge, particle size and/or ongoing The approach includes Kelvin’s law express influence on constant precipitates, Nernst’s calculate potentials from and relate experimentally measured zeta potentials. Calcium carbonate potential measurements well characterised high purity calcite been used model system validate calculated values. clarification change titration illustrates power tool for pathway prediction hence knowledge based tailoring reactions.
