Then the effects of the impurities in concentrated phosphoric acid on the nutrient content in diammoniumphosphate are discussed.
最后分析了浓磷酸中的杂质含量对磷酸二铵产品总养分的影响。

A new method is set up to determine the water-soluble and available phosphorus in diammoniumphosphate by the application of ultrasonic wave to solve the sample.
建立了超声波溶样快速测定磷酸二铵中的水溶性磷和有效磷的方法。
3
The physical forms in diammoniumphosphate are examined and their contents are quantitatively estimated. The calculated results show quite near to the actual analysis.
