About ABB monitors
The reduction solution is needed for ABB’s calorimetric monitors to measure silica in steam generation and demineralisation plants. The process involves a reaction between molybdate, sulphuric acid and silica to generate molybdosilic acid complexes, which have a yellow colouration. An acidic environment ensures minimal formation of other molybdate complexes and improves sensitivity. This is followed by a reduction, turning the yellow complex to blue, which is subsequently measured in the calorimeter. This measurements correlates with the concentration of silica in the original sample.
The process starts with the addition of sulphuric acid to lower the pH, after which molybdate is added to form a yellow complex if silica is present. A second acid solution (including sulphuric and citric acid) is added to further drop the pH and favour the subsequent reduction reaction.
In samples with high levels of phosphate, it’s advisable to increase the concentration of citric acid to reduce the risk of phosphate complexes which would incorrectly increase the final result. The reduction solution is added and yellow complexes turn blue, and the intensity of the colour measured by calorimeter.
