Überwachung und Kontrolle der Polyelektrolytkonzentration im System unter Verwendung fluorochromer Farbstoffe

摘要

The concns. of a polyelectrolyte (I) in aq. systems is monitored and/or controlled as follows: (a) a known or standard amt. of a fluorochromatic reagent (II) is added to a sample of the H2O; (b) light energy of a selected excitation energy for (II) is directed into the sample; (c) the intensity of light emitted about the fluorescence emission wavelength of (II) is measured and compared with a standard curve (comprising a plot of the fluorescence emission intensity of (II) in the presence of (I), against the concn. of (I)) to allow determination of (I).
