磷钼酸喹啉重量法测定磷矿石和磷精矿中五氧化二磷含量,方法准确可靠,是磷矿的仲裁分析法。本文探讨了用普通滤纸代替玻璃坩埚式滤器分析五氧化二磷含量的可行性。试验表明,用普通滤纸代替玻璃坩埚式滤器切实可行,方法精密度和准确度能满足常规分析要求。
燐鉬痠喹啉重量法測定燐礦石和燐精礦中五氧化二燐含量,方法準確可靠,是燐礦的仲裁分析法。本文探討瞭用普通濾紙代替玻璃坩堝式濾器分析五氧化二燐含量的可行性。試驗錶明,用普通濾紙代替玻璃坩堝式濾器切實可行,方法精密度和準確度能滿足常規分析要求。

Quinoline phosphomolybdate gravimetric determination of phosphorus ore and phosphorus pentoxide content in the concentrate,the method was accurate,reliable,and was the phosphate arbitration analysis,which corresponded with national standards GB/T 1871-80 and GB/T 1871.1-1995.International standard ISO 6598（Fertilizers-Determination of Phosphorus Content-Quinoline Phosphomolybdate Gravimetric Method） and the national standard GB 10512-89（Nitrate Fertilizer in the Determination of Phosphorus Quinoline Phosphomolybdate Gravimetric Method） were basically the same test procedure.It was used that quinoline molybdenum lemon ketone reagents,the glass filter of crucible type,and maintaining（180±2） ℃ constant temperature oven.Glass crucible-type filter was a special vessel.The feasibility of analysis of phosphorus pentoxide content was discussed by using ordinary filter paper instead of glass crucible filter.Tests showed that the method with an ordinary filter paper for analysis instead of glass crucible-type filter was practical,and its precision and accuracy met the requirements of GB/T 1871.1-1995.
