坚果与籽类食品中钼含量测定的方法探讨

Discussion on the determination method of molybdenum content in nuts and seeds

分别用石墨炉原子吸收光谱法和电感耦合等离子体发射光谱法对坚果与籽类食品中钼含量进行测定,探讨了微波消解条件、升温条件、基体改进剂等对原子吸收光谱法的影响,以及微波消解条件、气流量条件选择对电感耦合等离子体发射光谱法的影响,分析讨论了两种测定方法的检测特点。

The molybdenum content in nuts and seeds was determined by graphite furnace atomic absorption spectrometry and inductively coupled plasma emission spectrometry,respectively.The effects of microwave digestion conditions,heating conditions and matrix modifiers on atomic absorption spectrometry,and the effects of microwave digestion conditions and air flow conditions on inductively coupled plasma emission spectrometry were discussed.The detection characteristics of the two methods were also analyzed.
