火焰原子吸收光谱法测定肥料中的铬

Determination of Cr Content in the Fertilizer by Flame Atomic Absorption Spectrometry

铬是人体必需的微量元素,但铬缺乏或过量对人体和动物产生严重危害。肥料中铬含量过高,会使土壤、农作物及蔬菜等受污染,造成对人类和动物的危害。用原子吸收火焰法测定肥料中铬含量,操作简便、快速、准确。

Cr is an essential trace element of human,lack or excess of chrome has serious damage to human and animals.High Cr content in the fertilizer can pollute soil and crops,which can produce serious damage to human and animals.In this paper,the flame atomic absorption spectrometry was used to determine Cr content of the fertilizer.The method is simple,efficient and accurate.
