Iron and acid determination in etching
baths
Metrohm UK has developed ProcessLab which automatically determines free acid, total acid, Fe2+ and Fe3+ ions in etching baths for the steel industry.
Acid etching baths are used for oxide removal and cleaning of the surface of different types of steel To keep the bath in an optimum condition the Fe2+/Fe3+ and free acid/total acid ratios must be maintained within certain limits

Metrohm has combined the best aspects of laboratory and online systems to produce the 875 ProcessLab: a fully customised, automated at-line system for analytical testing.
Auxiliary substances like hydrogen peroxide are added to influence the Fe2+/Fe3+ ratio, which is responsible for a constant activity of the bath.
The quality of the end products depends directly on the correct composition of the etching bath.
Keeping these parameters in an optimum range results in a permanently higher quality and at the same time lowers costs due to lower reagent consumptions.
ProcessLab from Metrohm UK automatically evaluates the desired bath parameters (free acid, total acid, Fe2+ and Fe3+).
Due to the flexibility offered by ProcessLab the determination of hydrogen peroxide can be integrated very easily.
Features/general information: all 4 parameters in one system, one button analysis, easy to operate for semi-skilled staff, direct feedback of the measured results to the process control system, can be used for different baths without additional costs, additional parameters can be measured at minimum costs (eg H2O2), the method can be used in the lab as well.
