In steel production, the pickling process aims at preparing the steel surface for subsequent process steps. These pickling baths contain HCl, H2SO4, HNO3, HF, H3PO4, Fe2+, Fe3+. For reproducible surface treatment, bath composition has to be continuously monitored. This is best done with titration using rugged Metrohm Process Analyzers, as described in the following.
