原子吸收光谱法测定复混肥料中氯含量

Method of Determining Chlorine Content in the Mix Fertilizer by Atomic Absorption Spectrumetry

提出用空气—乙炔火焰原子吸收光谱法测定复混肥料中氯含量的方法,采用加入过量的硝酸银溶液,原子吸收光谱法测定剩余的银离子,间接测量氯含量。该方法具有较高的灵敏度,很好的重现性,操作简单,容易掌握,干扰少等特点。

The method to measure chlorine content with the atomic absorption spectrum of air - acetylene games in the mix fertilizer was introduced in this paper. In this method excess silver nitrate was added to react with Cl^-, then the excess Ag^＋ was detected by the atomic absorption spectrum technique, at last,it win give us the chlorine content indirectly. This method has many characteristics, such as higher intelligent degree, simple operation, easily controling, few interference.
