The precipitation of Ca3(PO4)2 scale on pipe surfaces widely occurs in numerous industrial processes. For the control of Ca3(PO4)2 scales, a novel environmentally friendly type of scale inhibitor Maleic anhydride (MA) - allypolyethoxy carboxylate (APEM) was synthesized. Structures of APEG, APEM, and MA-APEM were identified by FT-IR. MA-APEM possess excellent Ca3(PO4)2 inhibition, approximately 96.7 % at threshold dosage of 6 mg/L, and it also have superior ability to iron (III) dispersion in solutions approximately 24.3 % in the presence of MA-APEM when the dosage exceeds 6 mg/L. Inhibitor of MA-APEM can be used safely in cooling water systems.
