    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.

    摘要： A method for determining the presence of ferrous ion in boiler waters is described. The method can be used to directly measure the rate of corrosion occurring in boiler waters, and can measure the corrosion rates in the presence of boiler water treatment chemicals. The method uses a complex formed between only ferrous ion and a chemical 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine-p,p'-disulfonic acid monohydrate reagent.

F.; and adding a scale inhibitor and/or iron disperant to the feedstream in an amount between about 0.002 ppm per ppm hardness (as CaCO.sub.3) of the feedstream to about 0.005 ppm per ppm hardness (as CaCO.sub.3) of the feedstream, the scale inhibitor comprising a water-soluble organic phosphonate and an N-substituted acrylamide polymer containing an amide structure as follows: ##STR1## where R.sub.2 is hydrogen or methyl, R.sub.1 is a hydrogen or an alkyl, and R is alkylene or phenylene and X is sulfonate, (poly) hydroxyl, (poly) carboxyl or carbonyl, and combinations thereof, with the weight ratio of polymer to phosphonate being within the range of about 0.2:1 to about 2:1; provided that when X is sulfonated then R--X-- is selected from the group consisting of sulfomethyl and 2-sulfoethyl.
