Determination of sulphate
Sulphate reacts with barium ions forming a precipitate of barium sulphate. Under defined conditions this turbidity can be used for concentration measurements.
The determination of sulphate ions is of special importance to evaluate the aggressiveness of a water towards concrete. Sulphate, a component of natural water, is formed in many manufacturing processes and is found in waste waters even after neutralisation.
