“…An important example of bench-scale and industrial scale evaluation of the antiscaling and fluorescent activity of a novel 1,8-naphthalimide tagged polyacrylate PAA-F1 has been published by our research group recently [91]. The ability of fluorescent 1,8-napthalimide-tagged polyacrylate PAA-F1 to serve as an "on line" indicator of polymeric scale inhibitor concentration has been tested in dynamic bench scale tests operating with EMEC facility, and in an industrial-scale in situ experiment run at a "Rosinka 10/20" cooling tower that provides the circulating water cooling of heat exchangers at rectification columns of ECOS-1 Co. site in Staraya Kupavna city, Russia, with a total cooling water volume of 4.5 m 3 , Figure 11.…”

Fluorescent-tagged scale inhibitor application is a new trend in water treatment. An increasing interest to the fluorescent antiscalants is associated with a need of a better scale inhibitor concentration control in industrial applications: the concentration of antiscalants in the circulating system is usually changed by evaporation of water, reagent sorption on the pipe surfaces and on scale particles, as well as by a periodical discharge of the circulating water with some deposit. This paper considers synthesis, properties and industrial applications of antiscalants bearing a fluorescent fragment. A special focus is done on the covalent implementation of the fluorescent fragment into the polymer matrix, performed in two different ways: (a) the first one includes attachment along with the polymer formation process; (b) the second one is based on the fluorophore binding to the ready-made polymer matrix. An attachment of a fluorescent fragment to the bisphosphonate is also described. Besides the issues of antiscalant concentration monitoring in industrial facilities, the unique opportunity of the scale inhibition theory development via the direct visualization of fluorescent-tagged scale inhibitors in various scale formation processes is demonstrated. A recent progress in scale inhibition mechanism understanding due to an antiscalant visualization in situ is highlighted.

“…Most of these problems could be successfully solved by the application of fluorescent-tagged antiscalants, which have gained increasing interest over the past decades [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ].

“…Indeed, the precise monitoring of polycarboxylates is a challenge for water treatment technologies. Fluorescence detection has therefore attracted increasing attention as a powerful tool in chemical sensing due to its high sensitivity and simplicity [ 13 , 14 , 15 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. However, the “online” control of phosphonate concentration in water recirculation systems is also an actual issue [ 11 , 30 ].…”

Equipment scaling leads to reduced production efficiency in a wide range of industrial applications worldwide. Various antiscaling agents are currently commonly used to mitigate this problem. However, irrespective of their long and successful application in water treatment technologies, little is known about the mechanisms of scale inhibition, particularly the localization of scale inhibitors on scale deposits. The lack of such knowledge is a limiting factor in the development of applications for antiscalants. Meanwhile, fluorescent fragments integrated into scale inhibitor molecules have provided a successful solution to the problem. The focus of this study is, therefore, on the synthesis and investigation of a novel fluorescent antiscalant: (2-(6-morpholino-1,3-dioxo-1H-benzo[de]isoquinolin-2(3H)yl)ethylazanediyl)bis(methylenephosphonic acid) (ADMP-F) which is an analog of the commercial antiscalant: aminotris(methylenephosphonic acid) (ATMP). ADMP-F has been found to effectively control the precipitation of CaCO3 and CaSO4 in solution and is a promising tracer for organophosphonate scale inhibitors. ADMP-F was compared with two other fluorescent antiscalants—polyacrylate (PAA-F1) and bisphosphonate (HEDP-F)—and was found to be highly effective: PAA-F1 > ADMP-F >> HEDP-F (CaCO3) and PAA-F1 > ADMP-F > HEDP-F (CaSO4·2H2O). The visualization of the antiscalants on the deposits provides unique information on their location and reveals differences in the “antiscalant-deposit” interactions for scale inhibitors of different natures. For these reasons, a number of important refinements to the mechanisms of scale inhibition are proposed.
