Determination of Fe2+, Fe3+, total and
free acid
To keep the etching bath in an optimum condition the Fe2+/Fe3+ and free acid/total acid ratios must be maintained within certain limits
Acid etching baths are used for oxide removal and cleaning of the surface of different types of steel 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.
This bulletin describes the monitoring of an etching bath in the steel industry.
ProcessLab offers a solution that 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. Request a free brochure from Metrohm UK ...
