Placket-Burman Optimization of KAl(SO4)2

Year: 2023

Presenter Name: Emily Hiatt

KAl(SO4)2 crystals were synthesized and analyzed using Plackett - Burman Optimization, comparing the success of crystallization between viscosity, temperature, and concentration. The Plackett-Burman optimization is used for analyzing a few variables with reproducibility without having a massive amount of trials. Adapting this to experimentation and the lab is difficult, given the lack of technology available to make it accessible. For our experimentation, KAl(SO4)2 synthesis was manipulated in three ways - viscosity (water, propyl glycol, and glycerine), temperature (5C, 22C, and 45C), and concentration (0.2, 0.4, 0.6 g/mL). After a week of crystallization, the middle values of each variable performed the best and had the most measurable crystals. All crystals were measured with an optical microscope for size, and with x-ray diffraction for crystallinity. In order to make Plackett-Burman accessible, a program has been developed to automatically create the trials necessary to run any experiment necessary.
