The effect of electromagnetic field on silver iodide sols stability

Abstract

It is shown that the influence of the ultrahigh-frequency electromagnetic field on purified water leads to a significant increase in its electrical conductivity and pH. The effect can be interpreted as a change in the supramolecular organization of water. The kinetics of the formation of nuclei of the crystalline phase in irradiated water by the example of silver iodide sols was studied by turbidimetry. It is shown that in the irradiated water the growth of AgI crystals slows down, which is noticed as a slower decrease in the light transmission of the sol in time. The effectiveness of electromagnetic influence depends on the frequency and time of irradiation so that the maximum effect is achieved at the field frequency of 170 MHz and at the irradiation time of 3 hours. Destruction of the sols prepared with irradiated water takes place on the 4th day, while in the control samples it begins after 24 hours. It is assumed that in the irradiated water the growth of crystalline nuclei slows down due to a change in the surface tension and a decrease in AgI solubility
