硫酸铵中氮含量的快速测定

Rapid Determination of Nitrogen Content in Ammonium Sulfate

采用国家标准《GB/535-1995,硫酸铵》规定的方法测定硫酸铵中氮含量,耗时较长,操作繁琐,通过实验改用全自动凯氏定氮仪快速测定硫酸铵中氮含量。该方法操作简便,检测时间短,其准确度和精密度符合国家标准的要求,可大批量测定硫酸铵中氮含量。

The article mainly uses the method specified in the national standard"GB/535-1995,ammonium sulfate"to determine the nitrogen content in ammonium sulfate,which takes a long time and is cumbersome to operate.It uses an automatic Kjeldahl tester to quickly determine sulfuric acid The method has simple operation and short detection time,and its accuracy and precision meet the requirements of national standards.It can determine the nitrogen content of ammonium sulfate in large quantities.
