The two fluorescent monomers N ‐allyl‐4‐methoxy‐1,8‐naphtalimide ( F1 ) and N ‐allyl‐2‐(6‐hydroxy‐3‐oxo‐3 H ‐xanthen‐9‐yl)benzamide ( N ‐allylamidefluorescein, F2 ) have been synthesized and then conjugated to either polyacrylate (PAA) or to a co‐polymer of fumaric and acrylic acids (MA‐AA) to give four novel fluorescent‐tagged antiscalants: nonbiodegradable PAA‐F1, PAA‐F2 and biodegradable MA‐AA‐F1 , MA‐AA‐F2 . All four reagents demonstrate the fluorescence intensity suitable for inhibitors monitoring with a detection limit within 0.40 mg dm −3 . A good linear relationship between antiscalant fluorescent intensity and its dosage is detected. PAA‐F1, PAA‐F2, MA‐AA‐F1, and MA‐AA‐F2 can be used for corresponding scale inhibitor content on‐line measurement. For some antiscalants, the fluorescence is found to be dependent on the background heavy metal ions normally present in the cooling water. This effect is explained by the corresponding complexes formation. PAA‐F1, PAA‐F2, MA‐AA‐F1, and MA‐AA‐F2 revealed a good antiscaling activity toward CaCO 3 and CaSO 4 deposition, comparable with that one of commercial polyacrylates. © 2017 Wiley Periodicals, Inc.
