In an attempt to control CaCO3 deposits in industrial recycling water
systems, a maleic anhydride-b-cyclodextrins-acrylic acid-8-hydroxy-1, 3, 6-pyrenetrisulfonic
acid trisodium salt (MA–b-CD–AA–PA) copolymer was synthesized by
free-radical polymerization. The structure of the copolymer was characterized using
FT-IR, 1H NMR, and TGA. The MA–b-CD–AA–PA exhibited an excellent ability
to control inorganic minerals, with 95.8 % CaCO3 inhibition at level of 10 mg l-1
MA–b-CD–AA–PA, which suggested that the prepared copolymer was an excellent
scale inhibitor. The copolymer showed the same fluorescence as pyranine. The
fluorescence intensity of the copolymer was directly proportional to its
concentration.
