Abstract: The aim of this work is to study the effect of a water-soluble copolymer, Acrylic acid–Oxalic acid–Allypolyethoxy carboxylate–8-hydroxy-1,3,6-pyrene trisulfonic acid trisodium salt (pyranine) (AA-APEM-APTA), APEM, and APTA were copolymerized with acrylic acid (AA) to synthesize APTA-tagged no phosphate and nitrogen-free CaCO3 inhibitor, AA-APEM-APTA. Structures of APTA, APEM, and AA-APEM-APTA were carried out by FT–IR. The observation shows that the dosage of AA-APEM-APTA plays an important role on CaCO3 inhibition. It can be concluded that the order of preventing the precipitation from flask tests was AA-APEM > AA-APEM-APTA > HPMA > PAA≈PESA. Relationship between AA-APEM-APTA’s fluorescent intensity and its dosage was studied. Correlation coefficient r of AA-APEM-APTA’s is 0.99672. The effect on the formation of CaCO3 was investigated with combination of scanning electronic microscopy, transmission electron microscope, and X-ray powder diffraction analysis. AA-APEM-APTA can be used to accurately measure polymer consumption on line besides providing excellent CaCO3.
