研究了牛骨作为种子材料在羟基磷灰石结晶中的适用性。实验用的种子晶体是用牛骨煅烧制备的。通过批量实验考察了初始钙浓度、pH、碱度、反应温度条件和煅烧温度对合成溶液的影响。实验结果表明，牛骨晶体播种法可以达到较好的除磷效果。根据反应后残余磷浓度与pH的高度相关关系，可以预测不同钙浓度和pH下的除磷率。通过速率常数分析考察了碱度、反应温度条件和煅烧温度对焙烧效果的影响。
The applicability of cow bone as a seed material in hydroxyapatite crystallization was investigated in this research. Seed crystal used for the experiments was prepared by the calcination of cow bone. The effects of initial calcium concentration, pH, alkalinity, reaction temperature condition, and calcination temperature were examined for synthetic solution by batch experiment. The experimental results showed that a good phosphorus removal could be achieved by cow bone crystal seeding. The phosphorus removal rate with various calcium concentrations and pHs could be predicted from high relationships between residual phosphorus concentration and pH (after reaction). The effects of alkalinity, reaction temperature condition, and calcination temperature were also examined by rate constant analysis.
