| 摘 要： | 根据Ｐｂ２＋能与ＰＯ＿４￣（３－）定量形成沉淀，过量的Ｐｂ２＋在ＮａＣｌＯ３－六次甲基四胺底液示波图上有敏锐切口的性质，报告了磷肥中有效磷含量测定的示波滴定新方法。该法与通用方法相比较，具有操作简便、测定快速、终点直观的优点。

| Abstract: | A new oscillographic titration method fro the determination of active phosphorus content in phosphate fertilizers is described. It is based upon precipitate formation of Pb2 with PO and the characteristic sharp incision by excess Pb2 on the dE/dt vs E curves in NaClO3-hexamine media.As compared with the conventional methods,the proposed method has the merits of simple operation, fast determination and sharp endpoint deflection. |
