A liquid capacitance cell was developed, tested, and utilized to accurately measure dielectric constants of polar molecules. Coupled with additional measurements of the refractive index, dipole moments of three different extraction reagents were determined. The extraction reagents are of interest for liquid–liquid extraction processes for metal ions, including treatment of used nuclear fuel. The dipole moment is a key parameter for accurate and successful simulation of these types of processes. In this work, we report on the measurements, the determined dipole moments, as well as details of the development of the cell, including design considerations and possible improvements.
