Abstract
Interest is reviving in the dielectric properties of liquids. The present paper is concerned with a specific group of polar liquids having electrical conductivities which lie in the intermediate range between those of insulating oils and those of liquids such as electrolytic solutions.
It has been found recently that ion exchange techniques provide a powerful means of purifying polar liquids. In this way, liquids have been deionised so effectively that their resistivities have been increased by three orders of magnitude as compared with previously published values.
Published work on this subject is summarised. Removal of trace impurities from liquids may help to clarify mechanisms of electrical conduction, charge injection, and charge exchange phenomena in polar liquids.
Preliminary results of investigations made by the authors are included in the article.
