工业碳酸钠中无机铵含量的测定

Inorganic ammonium content determination in industry sodium carbonate

阐述了工业碳酸钠中无机铵含量的测定原理,介绍了目视比色与分光光度两种测定方法,并以采用分光光度法测定的实例,说明选用分光光度法可以准确、及时地测出工业碳酸钠中无机铵的含量。

The determination principle and method of inorganic ammonium content in industry sodium carbonate are related,and two determination methods of visual color comparision method and spectrophotometry are introduced.Based on the actual example determination by spectrophotometry,it showed that the inorganic ammonium content in industry sodium carbonate could be determinated more accurately and rapidly by spectrophotometry.
