Gypsum crystallization kinetics in the presence of glutamic acid in MSMPR crystallizer

What is it about?

In this study, calcium sulfate dihydrate crystallization was performed in a MSMPR crystallizer at 2.5 pH, 65ºC in the absence and the presence of glutamic acid. The crystal size distributions, filtration rates and zeta potentials of the crystals obtained were measured and the crystals were analyzed by XRD, TGA-FTIR-MS and SEM. Furthermore, the growth rate of crystals was determined using ASL, C-R, MJ2, and MJ3 model. By comparison of the results of mean square error analysis, it was found that the MJ3 model was the best model to characterize the system.
