The effects of orthophosphate and tripolymers AA/AMPS/HPA on calcium carbonate scale are studied by using SEM, XRDand static scale inhibition method. The results showthat using orthophosphate alone has no effect on inhibiting calcium carbonate scale. AA/AMPS/HPA and orthophosphate have synergistic effects on inhibiting calciumcarbonate scale within certain concentration ranges. It proves that the synergistic effect decreases when the concentration of PO4 3- is over 6 mg/L. Proper amount of orthophosphate and AA/AMPS/HPA make the shape of calciumcarbonate change and has obvious inhibiting efficiency on calcite.
Key words： orthophosphate; calcium carbonate; scale inhibition; synergistic effects
