A Bridge Method for Measuring the Dielectric Relaxation of Conducting Solutions

  • M. M. Springer

A method is described for measuring the dielectric relaxation of conducting solutions in the kHz region with commercially available bridges and a cell with large variable electrode spacings. By calculating the difference of the measured impedances at successive frequencies and different electrode distances, impedances due to electrode polarization, lead inductance and stray fields could be eliminated from the measurements. The literature value of ε’ of 1 mM KC1 has been determined within two units down to 4.00 kHz. The complex dielectric and conductivity data of a dilute solution of polystyrene particles with high ionic conductivity have been measured.
