研究了在高pH值10.8时形成的磷酸钙相对锶的共沉淀作用。在此条件下得到的第一相为无定形磷酸钙(ACP)，在诱导期后转变为晶态羟基磷灰石(HA)。结果表明，这种转变和析出固相形态的变化，对锶的吸附量有显著影响。讨论了这一发现对磷酸钙共沉淀锶的实际应用可能产生的影响。
The coprecipitation of strontium by a calcium phosphate phase formed at an elevated pH 10.8 was investigated. The first phase obtained under these conditions in the amorphous calcium phosphate (ACP) which is transformed into crystalline hydroxyapatite (HA) after the induction period. Is has been shown that this transformation together with morphological changes of the precipitated solid phase, influences the amount of the sorbed strontium significantly. The possible consequences of this finding on practical application of coprecipitation of strontium by calcium phosphate have been discussed.
