A modelling approach to establish experimental parameters of a flow-through titration

A flow-through titrimeter with optical detection and the flow-through titration of sulphate have been studied by using control engineering methods. Qualitative chemical descriptions and systems analysis yield a model covering different precipitation rates of barium sulphate. The validity of the model is proved by comparing simulated and real experiments. Possible uses of the model are indicated. The signal of the titrimeter is shown to be independent of dilution and turbidity, because of the special detection arrangement
