Abstract
A polymer tagged with luminol is provided which enables the fluorescent or chemiluminescent detection of the tagged polymer at low concentrations. The chromophore may be covalently bonded to the polymer backbone without sacrificing the chromophore's fluorescent or chemiluminescent properties. The present invention has been found useful in the treatment and monitoring of industrial waters.
