TITLE:

MEASUREMENT OF MOLECULAR SOLUBILITY IN LIQUIDS IN REAL TIME BY WAVELENGTH MODULATION SPECTROSCOPY.

KEY WORDS:

Modulation, spectroscopy, solubility, molecules.

PAGES: 56
BIG AREA: Engenharias
AREA: Engenharia Elétrica
SUMMARY:

This thesis project explores a solubility measurement technique using Wavelength Modulation Spectroscopy (WMS). The technique allows the study of the molecular dynamics of transport between liquid-gas and/or gas-gas interfaces by measuring the concentration of specific molecules in the gas phase by WMS. Using a theoretical model for one or more interfaces and measuring the concentration data by WMS it is possible to calculate the partition coefficient in the steady state (equilibrium phase) and thus consequently obtain the solubility of the gaseous molecule in the liquid. In order to obtain the experimental data, the entire experimental setup of a first version of the experiment is being reassembled with improvements that should bring better precision and reproducibility of the measurements. It is expected that with a more stable and accurate system, the technique will be consolidated and applied in the most diverse sectors of interest: food industry (soft drink industry), fruit ripening, DGA analysis, pharmaceutical industry, biometric applications, oil industry, etc.
