在不同pH和缓冲条件下，测定了合成羟基磷灰石在10-3~10-2M磷酸盐和锶离子醋酸盐缓冲溶液中的溶解速率和表观溶解度。用物理模型对锶的作用进行了严格的检验，表明钙-锶磷灰石表面复合体可能控制着溶解反应的驱动力。
Dissolution rates and apparent solubilities for synthetic hydroxyapatite in acetate buffers containing phosphate and strontium ions in the range of 10-3 to 10-2 M were determined under various pH and buffer conditions. Critical examination of the role of strontium with a physical model suggests that a calcium-strontium apatite surface complex may govern the driving force of the dissolution reaction.
