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。
Chromium is an essential trace element of the human body, but chromium deficiency or excessive serious harm to human beings and animals. High levels of chromium in fertilizers can contaminate soils, crops and vegetables, causing harm to humans and animals. Determination of chromium content in fertilizer by flame atomic absorption spectrometry, easy to operate, fast and accurate.
