The purpose of the experiments was to determine the influence of the field frequency and amplitude of the field strength on the excitation phenomenon, and the study of the operating characteristics of the testing apparatus -a dividing cell. The dependences of the separation efficiency of solvated cations from the frequency of the external field and the excitation threshold of the phenomenon from the field strength in the separation cell are defined. State of the researchEarlier discovered phenomenon of selective drift of solvated ions under the influence of an external "asymmetric" electric field [1] for today found only one practical application in technology of the separation of cerium and yttrium cations formed during the investigation of the properties of spent nuclear fuel [2]. At the same time, the directions, in which the use of the phenomenon may bring a significant effect, sufficient clearly marked in a number of papers [3,4,5]. The main reason for the small number of practical uses of the observed phenomenon were two factors: a shallow study of the question of hardware implementation of technical systems that operate on the basis of the phenomenon, and the lack of experimental data on the influence of the electric field frequency on the effectiveness of separation processes solvated ions in moving (circulating) solutions. This paper presents the results that once again confirm the importance of the observed phenomenon, its stability and reproducibility, as well as enabling to create a relatively simple experimental installation for searching of application to phenomenon of selective drift of solvated ions under the influence of an external "asymmetric" electric field. The term "asymmetric" electric field was introduced in experiments on excitation of selective drift of ions [1] and has an important meaning as the "normal" sinusoidal potential does not cause the observed phenomenon. Experimental sectionBlock diagram of the experimental installation is shown in Figure 1. The main power source of variable frequency signal was audio-frequency generator GZ-109 1, the signal from which is fed to the input of pre-amplifier RUB2250 2 with its own power supply NES-100-12 3.
