Kupfersulfates) bis ungefähr l'8 Volt (Minimal-Zersetzungsspannung des Eisensulfates). Da aber die Oxydation der schwefligen Säure eine elektromotorische Kraft von ungefähr 1 Volt erzeugt, weiche der beabsichtigten Reaktion zugute kommt, so betragen die Grenzen der konstant zu erhaltenden Spannung ungefähr 0'2 und 0#8 Volt.
Bei der Behandlung von reinen Lösungen (D. R. P. Nr. 32866) muss eine Erwärmung aus dem Grunde stattfinden, um die bei gewöhnlicher Temperatur sehr geringe Dopolarisationswirkung der schwefligen Säure zu steigern, während nach dem vorliegenden Verfahren die Behandlung bei gewöhnlicher Temperatur stattfinden kann, denn die Depolarisationswirkung ist, selbst bei niedriger Temperatur genügend stark, wenn die schweflige Säure zugleich mit Eisensalzen in der Lösung enthalten ist, wie dies auch bei den nach vorliegendem Verfahren zu behandelnden Flüssigkeiten der Fall ist.

Copper sulphate) up to about 18 volts (minimum decomposition voltage of iron sulphate). But since the oxidation of the sulphurous acid produces an electromotive force of about 1 volt, which is of benefit to the intended reaction, the limits of the voltage to be kept constant are about 0.2 and 0.8 volts.
When treating pure solutions (DRP No. 32866), heating must take place in order to increase the dopolarization effect of the sulfurous acid, which is very low at normal temperatures, while according to the present process the treatment can take place at normal temperature, because the depolarization effect is sufficiently strong, even at low temperature, if the sulphurous acid is contained in the solution at the same time as iron salts, as is also the case with the liquids to be treated according to the present process.
