method for determining the salt inhibitor concentration in salt water with an ion selective calcium / magnesium electrode

摘要

The present invention relates to a method for determining a concentration of a deposit inhibitor in salt water, comprising an analysis with an ion-selective calcium / magnesium electrode of a first dialysed sample of salt water and a second dialyzed sample of salt water that has been supplemented with a known concentration of the deposit inhibitor. the invention also relates to a method for inhibiting scale in a plant containing salt water, comprising the steps of adding a scale inhibitor to salt water at a desired concentration, determining the actual concentration of the scale inhibitor in salt water, as above, and add additional deposit inhibitor to the salt water to adjust the desired concentration. the invention also relates to a device for determining a concentration of a deposit inhibitor in salt water by the method above, comprising a calcium / magnesium ion selective electrode, a dialysis unit and a dosage unit to supplement the inhibitor deposit in the second sample of salt water.
