摘要：
A new experimental method is employed to examine the dynamics and structure of solutions containing charged particles: electrolytes, colloid solutions, solutions of macromolecules etc. The method is based on the detection and analysis of the frequency characteristics of the acoustic signal excited in electrolytes when an external AC electric field is applied. A robust and sensitive detection scheme is used to detect weak electroacoustic signals in electrolytes. Electroacoustic spectra obtained in simple electrolytes, KCl, LiI and KH2PO4, in the low frequency range (10 Hz-1 kHz) have been analyzed. The mechanisms of excitation of electroacoustic signals and their influence on the obtained resonance in electrolytes have been discussed.
