摘要

Electrolyte solution has an effect on growth and nonlinear optical properties of glycine crystals at certain conditions. The solubility of glycine in MgCl2-H2O solutions with molality from 0.5 to 3.5 was investigated by a dynamic method from (283.15 to 333.15) K. The solubilities of MgCl2 center dot 6H(2)O in glycine-water solution with molalities from 0.08 to 0.67 were also measured by the same method from (293.15 to 323.15) K. For model validation, the solubility of glycine in mixed NaCl-MgCl2 solutions was also measured. The solubilities of both glycine and MgCl2 center dot 6H(2)O solids were observed to increase with increasing temperature and concentration with respect to one another, acting as solutes. The OLI correlation with an existing model shows large errors in the solubility calculation for the glycine-NaCl-MgCl2-H2O system. A self-consistent model using a unified set of model parameters obtained by regressing the solubility of glycine in single salt systems was developed. The model can accurately predict the solubilities of glycine in mixed NaCl-MgCl2 solutions with average absolute deviations lower than 2.5%.
