【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2.241 g MAP晶体。SEM扫描谱图显示:沉淀物的主要成分为磷酸铵镁晶体。更多还原

【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,2.241 g MAP crystal was prepared.The SEM analyses showed that the composition of the precipitate was mainly magnesium ammonium phosphate.更多还原
