摘要
The present invention relates to a method for determining a concentration of a scale inhibitor in a salt water comprising an analysis with a calcium/magnesium ionselective electrode of a dialyzed first sample of the salt water, and a dialyzed second sample of the salt water which was supplemented with a known concentration of the scale inhibitor. The inventon further relates to a method for inhibiting incrustation in a plant which contains a salt water comprising the steps of adding a scale inhibitor to the salt water at a desired concentration, determining the actual concentration of the scale inhibitor in the salt water as above, and adding further scale inhibitor to the salt water to adjust the desired concentration. The invention further relates to a device for determining a concentration of a scale inhibitor in a salt water by the method above comprising a calcium/magnesium ionselective electrode, a dialyzing unit, and a dosage unit for supplementing the scale inhibitor to the second sample of the salt water.
