不同阻垢剂对方解石和磷酸钙表面电位的影响

Effects of Different Scale Inhibitors on the Surface Potentials of Calcite and Calcium Phosphate

摘要: 采用微电泳法考察了１５种阻垢剂对方解石和磷酸钙颗粒表面电位的影响。实验结果表明，在各种药剂中，丙烯酸／２丙烯酰胺基２甲基丙磺酸／次磷酸调聚物对难溶盐表面电位影响最大，乙二胺四乙酸二钠盐的影响最小。乙二胺四甲叉膦酸的溶垢能力和对表面电位的影响都较强。各种药剂对两种难溶盐表面电位影响的排序差异不显著。根据配位化学和表面化学原理解释了实验结果。

Abstract: The effects of fifteen scale inhibitors on the surface potentials of calcite and calcium phosphate are examined using microelectrophoretic technique. Among these inhibitors, AA/AMPS/POCA has the strongest effect on the surface potentials of the sparingly
