Removal Properties of Ionic Substances by Electric Double-layer Adsorption using Activated Carbon Electrodes

摘要

Various kinds of electrolytes were removed to utilize the principle of the electric double-layer using the activated carbon electrode. It was easy to be removed in various sulfates and nitrate in the order of alkali metal, alkaline earth metal and transition metal. Though the ammonium salt removed over 75 percent, in phosphate and carbonate arc hard to be removed. This reason is based on hydrolysis and ion-exchange reaction. In the multicomponent system, it was easy to tend to remove large as electrolyte of the ionic migration speed.
