You might consider this really old stuff:
H. Sack (1926). "Uber die Dielektrizitatskonstante von Elektrolytlosungen."
Physikalische Zeitschrift 27: 206-208.

H. Sack (1927). "Uber die Dielektrizitatskonstanten von Elektrolytlosungen
bei geringen Konzentrationen." Physikalische Zeitschrift 28: 199-210.
