MONITORING AND IN-SYSTEM CONCENTRATION CONTROL OF POLYELECTROLYTES USING FLUOROCHROMATIC DYES |
摘要 |
Concentration of a polyelectrolyte in the water of an aqueous system is controlled by first withdrawing a sample of the water and adding a known or standard amount of a fluorochromatic reagent to the sample. Then light energy is directed into the sample whereby light energy of a selected excitation wavelength for the fluorochromatic dye is available for absorption by the fluorochromatic reagent. The intensity of light emitted about a selected emission wavelength for the fluorochromatic reagent is measured and the intensity of the emitted light is compared to a standard curve, comprising a plot of fluorescence emission intensity of the fluorochromatic reagent in the presence of a polyelectrolyte versus concentration the polyelectrolyte. The concentration of the polyelectrolyte in the sample of water is determined from the comparison. |
