Аннотация:Both phosphonate- and polymer-based scale inhibitors have a broad spectrum of applications
in water treatment technologies. However, the “online” monitoring of antiscalant
content in an aqueous phase is still a challenge for researchers. A possible solution is
provided by the fluorescent markers added to the feeding water. These can be either an
antiscalant tagged or may represent the independent species. The review summarizes
both the advantages and the drawbacks of these approaches along with such markers’
classification, with a special emphasis on the novel fluorescent-tagged phosphonates.
Besides, some unique opportunities provided by the fluorescent-tagged antiscalants for
reverse osmosis membrane mapping, scale inhibition traceability, and a scale inhibitor
localization in a circulation water facility are also considered and discussed.
