Abstract
The metastable zone width (MSZW) data for aqueous glycine solutions at various saturation temperatures 308–328 K are experimentally measured using the turbidity probe in this work. The integral model based on classical nucleation theory is applied to determine the pre-exponential factor and interfacial energy using the measured MSZW data. It is found that the MSZW data of aqueous glycine solutions are fitted well to the integral model. The results indicate for glycine that the interfacial energy decreases with increasing temperature while the pre-exponential factor increases with increasing temperature. For comparison, self-consistent Nyvlt-like equation and classical 3D nucleation theory approach are also applied to determine the nucleation kinetics of glycine from the measured MSZW data.
