APPARATUS FOR DETERMINING THE REDOX POTENTIAL DURING THE REGENERATION OF CONTAMINATED, AQUEOUS SULPHURIC-ACID WASTE IN PAULING APPARATUSES

摘要

1. Equipment for determining the redox potential of the contents of the vessel and for controlling the addition of oxidants on regeneration of contaminated water-containing waste sulfuric acid in Pauling apparatus ; the boiler (2) of the Pauling apparatus forming an electrode and being connected to a reference electrode (12) via an electric bridge (6), wherein a cation exchange membrane (10) for spatial separation of the two electrodes (2, 12) is arranged in the electric bridge.
