Date Nov. 14, 1991.In the electrochemical regeneration of chromosulfuric acid, the chromium (III) sulfate solution containing sulfuric acid is fed under pressure into the electrolysis cells. In this way malfunctions in production are reduced. Variations in the amount of electric current available can be absorbed flexibly. The chromosulfuric acid is produced with constant quality.
