镉对人体具有多种毒性,由于花生对镉元素强烈的富集特性,许多国家对花生中镉含量进行0.1 mg/kg的限量要求。选用一种快捷、稳定、准确的检测方法检测花生中镉含量具有重要意义。目前检测食品中镉的国标方法有石墨炉原子吸收光谱法、火焰原子吸收光谱法、比色法和原子荧光法,还有电感耦合等离子体-质谱(ICP-MS)法等非国标方法。比色法灵敏度低,无法满 Cadmium has a variety of toxic effects on the human body. Due to the strong enrichment of cadmium by peanuts, many countries have limited requirements for 0.1 mg / kg of cadmium in peanuts. It is of great significance to choose a fast, stable and accurate detection method to detect the content of cadmium in peanut. At present, the national standard methods for the determination of cadmium in foods include graphite furnace atomic absorption spectrometry, flame atomic absorption spectrometry, colorimetric and atomic fluorescence spectrometry, and non-national standard methods such as inductively coupled plasma mass spectrometry (ICP-MS). Colorimetric sensitivity is low, can not be full
