Preparation and investigation of the scale inhibition performance of AA-AMPS-HPA

The scale inhibitors with sulfonic acid groups have excellent scale inhibition performance.They have better scale inhibition performance and wider applications than that of the unilateral inhibition because of their synergies with other scale inhibitors.The applications in the industrial water treatment of AA-AMPS-HPA required the investigation of its scale inhibition performance under different conditions.Herein,the effect of concentration of scale inhibitor,Ca~(2+),alkalinity and temperature on the scale inhibition performance of AA-AMPS-HPA was systematically studied.The experimental results showed that the copolymer was an excellent inhibitor against the deposition of CaCO_3.Moreover,when the concentration of Ca~(2+) was 371.2 mg/L and the concentration of scale inhibitor was 2.5 mg/L,its inhibition rate of AA-AMPS-HPA could reach 93.4%.
