摘　　要：通过气相分子吸收光谱法测定大量元素水溶肥中总氮的含量,并与传统的蒸馏后滴定法进行比较,结果相近。表明了气相分子吸收光谱法完全可以满足分析要求,并且该方法通过全自动气相分子吸收光谱仪操作更简单、步骤少。The content of total nitrogen in macronutrient water soluble fertilizer was determined by gas-phase molecular absorption spectrometry. This method was compared with the traditional titrimetric method after distillation, and the results were similar. It was shown that the gas phase molecular absorption spectrometry method could fully meet the requirements of the analysis, which was more simple and with fewer steps.

关 键 词：气相分子吸收光谱法 大量元素水溶肥 总氮
