ABSTRACT:
A concentration-fluctuation responsive regulation of water treatment agent feed is achieved by adding an incipient to a sample whereby a concentration indicator is formed. Such a concentration indicator comprises a combination of the incipient reagent and a substantially nonfluorescent water treatment agent. The concentration indicator is then monitored by fluorescence analysis of the sample to determine at least one fluorescence emission value that can be correlated to an in-system concentration of the water treatment agent. The fluorescence emission value measured in then correlated to the in-system concentration of the water treatment agent.
