摘要采用正交设计法对磷酸铵镁（MAP）的生成进行了研究。方差分析结果表明：在MAP晶体的形成过程中，溶液的pH值、初始P浓度（C₀）、以及二者的交互作用是MAP形成的显著性因素，对MAP的形成起决定性作用。依据各因素K值的大小，确定了MAP生成工艺的最优方案为A₃B₃C₃D₂E₁F₂。在最优方案条件下，制备获得2.241gMAP晶体。SEM扫描谱图显示：沉淀物的主要成分为磷酸铵镁晶体。

Abstract: The orthogonal design method was used to study the formation of magnesium ammonium phosphate (MAP) crystal. The results of variance analysis showed that the pH value of solution, initial P concentration (C₀), and its interaction are the significant factors for the formation of MAP crystal, which play the decisive roles in these process. According to the K values of factors, the optimal formation process of MAP was determined as A₃B₃C₃D₂E₁F₂. And under the optimal condition, 2.241g MAP crystal was prepared. The SEM analyses showed that the composition of the precipitate was mainly magnesium ammonium phosphate.

Key words: the orthogonal design method magnesium ammonium phosphate (MAP) the significance of the condition optimal process
