This project aimed to optimize the intercalation process for non-charged UV-filters in Zeolite L as well as characterize the intercalated products using different analytical technologies. UV-Visible, Fluorescence, Raman and Infrared Spectroscopy have all been tested to characterize the intercalated products. Of these, UV-Visible Spectroscopy of the washing solution provided the best indirect characterization for intercalated products. To optimize the intercalation process, loading rates were improved by varying the experimental conditions: dispersion time, size, temperature, heating time, and humidity. This project will contribute to the future work of the Meso Sun sunscreen project.
