International Journal of Chemical Engineering and Applications, Vol. 6, No. 3, June 2015 The Scale Inhibition Performance and Mechanism of Polyepoxysuccinic Acid for Calcium Phosphate Wu Lei, Wenyan Shi, and Gang Chen  scale inhibitors. Up to now, the research, development and Abstract—The static scale-inhibiting method was employed to performance evaluation of new scale inhibitors still mainly investigate the scale inhibition performance of rely on experimental and experience extrapolation methods, polyepoxysucci-nic acid (PESA) on calcium phosphate, and which will be prone to bring on the waste of time, manpower molecular dynamics (MD) method was used to simulate the and material resources. However, the experimental results interactions between PESA and (001), (010) surfaces of hydroxyapatite (HAP, the most thermodynamically stable phase could not provide us enough microscopic details about how of calcium phosphate) in aqueous solution. The results show that the scale inhibitors interact with the inorganic scale crystal, the scale inhibition efficiency of PESA increases as the increase and the interaction mechanism is still not clear. In contrast, in the concentration and PESA possesses better scale inhibition molecular dynamics (MD) simulation can be used to obtain performance compared with PAA while poor performance more detailed insights into the scale inhibition mechanism and compared with POCA. Moreover, PESA molecules adsorb on the surfaces rather
