Abstract :

In the field of water treatment scale inhibitors are gaining an increasing interest mostly in the last decade. The water treatment technologies use fluorescence phenomenon for the oil components control in wastewater, gaseous oxygen monitoring in waste waters, water leaks in industrial pipelines, for the total bacterial count and for on-line scale inhibitors content monitoring. Besides, the problem of a scale inhibition mechanisms is still actual and requires applications of fluorescent-tagged inhibitors. Both phosphonate- and polymer-based scale inhibitors are gaining nowadays a very broad spectrum of applications in water treatment technologies. However, the â�?�?on lineâ�? monitoring of an 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. In this research we present the results of recent studies performed in our research group. We managed to synthesize two different types of fluorescent-tagged inhibitors: polymer- and phosphonate-based ones (scheme 1), both containing naphtalimide as a fluorescent core. Fluorescent scale inhibitors of both types were thoroughly tested in our research group and showed excellent results providing ability to use them for on-line scale inhibitors content monitoring. The authors would like to thank the Russian Foundation for Basic Research (Project No. 17-0800061) and partly the Russian Scientific Foundation (Project 18-13-00144).
