Description
Water plays an important role in the environment through the interaction with coexisting chemical species. In this study we developed the simple and easy method of dielectric relaxation spectroscopy for the final purpose of the estimation of structure and dynamics of water in the environment.
We made a Teflon disk cell for liquid. The disk is 11mm in diameter and 1.5 to 2.7mm in height. Ahole of 5mm in diameter was hollowed out in the center of the disk and the bottom was sealed with copper leaf. In the measurement of electrical capacity, the cell filled with liquid (O.03 to O.05<cm>^^^3) was inserted between two metaldisk electrodes. We measured the electrical capacities of some solvents and solvent mixtures covering 1MHz to l8GHz frequencies by using this celland correlated the values with dielectric constants inliteratures
We also discussed the dielectric relaxation of alcohols and the influence of solvent-solvent interactions on the electrical capacities of solvent mixtures.
We can measure the electrical capacities to precision of ±1.5% by this method. The advantages of this method are as follows.
1. The measurement is simple and easy.
2. Only a small amount of liquid (O.03 to O.05<cm>^^^3) is required.
3. The time of measurement is short.
