| 中文摘要: |
| 报告了洗衣粉中磷测定的示波滴定新方法.洗衣粉样品经处理后,磷转化为磷酸根,Pb2+能与PO43-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. |
| 英文摘要: |
| A new oscillographic titration method for the determination of phosphorus content in laundry powder is described. It is based precipitate formation of Pb 2+ with PO 4 3- and the characteristic sharp incision by excess Pb 2+ on the dE/dt-E curves in NaClO 3 - hexamine media. |
