【摘要】：以磷酸、硫酸锰和硫酸铵为原料采用液相沉淀法制备磷酸铵锰,系统考察了反应温度、pH值、搅拌速率、反应时间、磷锰摩尔比n(P)∶n(Mn)和氮锰摩尔比n(N)∶n(Mn)对产物纯度的影响,结合正交试验优化,获得的磷酸铵锰的纯度大于99%,产率大于98%,并测定了其在100mL 2%柠檬酸中的溶解度及堆密度、休止角、pH值及吸湿性等,为磷酸铵锰的工业化生产及使用提供指导。
[Abstract]:Manganese ammonium phosphate was prepared by liquid-phase precipitation from phosphoric acid, manganese sulfate and ammonium sulfate. The effects of reaction temperature and pH value, stirring rate, reaction time, molar ratio of phosphorus to manganese (n (P): n (Mn) and molar ratio of nitrogen to manganese (n (N): n (Mn) on the purity of the product were investigated. Combined with orthogonal test, the purity of manganese ammonium phosphate was more than 99 and the yield was more than 98. The solubility and bulk density of manganese ammonium phosphate in 100mL 2% citric acid, the angle of repose, pH value and hygroscopicity were determined. To provide guidance for the industrial production and use of manganese ammonium phosphate.
