A novel fluorescent-tagged scale inhibitor, maleic anhydride–oxalic acid–allypolyethoxy carboxylate–8-hydroxy-1,3,6-pyrene trisulfonic acid trisodium salt (pyranine) (MA–APEM–APTA) was synthesized by maleic anhydride (MA), oxalic acid–allypolyethoxy carboxylate (APEM) and 8-hydroxy-1,3,6-pyrene trisulfonic acid trisodium salt (APTA). Structures of APTA, APEM, and MA–APEM–APTA were carried out by FT-IR...
