ELECTRIC PROPERTIES OF WATER

Abstract

The paper considers the dynamics of water exposure to an electric field of low intensity (up to 3.0 V). It has been established that the process of changing the electric current in an aqueous medium is exponential: the higher the applied voltage, the higher the exponent is located above the x-axis. It is shown that the exponents have time constants within 60 s, moreover, a change in the polarity of electrodes has a slight effect on their values. It is determined that the presence of impurities in water affects the position of the exponents. The cleaner the water is, the closer the exponent is to the x-axis. The effect of the polarity of electrodes on the dynamics of changes in the electric current when the electrode system is connected to a constant current source is studied. As a result of this process, the steady-state current values depend on the applied voltage. It is found that the difference in steady-state current values between the electrodes with substantially changing polarity changes in value and sign depending on the the applied voltage. It is noted that the highest indicators of the difference of the steady-state values of current when the polarity of the coaxial system of graphite electrodes is changing are observed near the electric potential value of the experimental system determined by the standard electrolysis potentials of water and graphite. The results obtained can be used in research and design of electro-hydraulic installations and water electroactivators.
