摘要
本文报道利用气相分子吸收光谱仪快速测定水中凯氏氮的方法。线性区间内该方法具有线性关系好,较高的精密度和准确度。该方法具有分析速率快、干扰小等优点,可应用于大批量水样分析。
In this report, a more rapid method for kieldahl nitrogen determination is reported using gas phase molecular absorption spectrometer. This method has high precision and accuracy as well as good linear relations in analysing range. The method has many advantages such as faster rate analysis and little interference.It can be used in analysising large quantities of samples.
