Abstract

This was an OURE project conducted by Austin Ramsey under the supervision of Dr. Klaus Woelk (advisor) and Dr. Rex Gerald (Senior Research Scientist, Chemistry Department). The purpose of the project was to investigate the usage of ionic liquids for dehumidifying air. The ionic liquid that was tested was 1-ethyl-3-methylimidazolium ethyl sulfate produced by BASF. A sample was placed in a custom built humidity control chamber which was run autonomously by a microcontroller. The ionic liquid was shown to adsorb large quantities of water from the atmosphere and then to release water when placed in an environment with less than twenty percent relative humidity.
